Repairs made to 8.2 for 8.3
_______________________________________________________
**Interface**

1) It is now possible to SAVE and GET programs without
line numbers. This is an option on the Save As dialog box.

2) It is now possible to select a section of code and
using the Edit|Comment menu item, comment out an entire
section of code.

3) An environment setting for "running with errors" has
been added. With this turned off, a warning dialog box
appears when attempting to run a program with syntax
errors. With this setting on, programs with syntax errors
may still be run.

4) Opening a non PROG or ASCII file now gives a warning
when more than 25 errors are encountered.

5) The change MSI dialog has been changed to allow direct
keyboard entry.

6) RENumber has been added as an option to the Edit menu

7) View|File Statistics now display the number of lines with
syntax errors.

8) Wait cursors now appear while the program is doing
intense editor related operations such as opening,
saving, etc.

9) Ctrl+Alt+D now appears as the assigned accelerator key
for the Device setup dialog. The Device setup dialog is
now accessed through the Tools menu item.

10) Accelerator key Ctrl + E was added to toggle Edit
mode on and off.

11) Alt-F6 is now properly assigned in KBD CMODE ON when
using Legacy Keyboard mode.

12) Clicking the toggle edit mode button while the child
window is minimized no longer causes an application error
to occur.

13) A history buffer was added to the Find, and Replace
dialogs.

14) Some editor keyword coloring was corrected.

15) Corrected a problem with DELeting large blocks of code.

16) The general speed of the editor has been increased.

17) Speed in scrolling in very large programs has been
greatly increased.

18) The -geometry command line startup switch has been
fixed to allow dimensions less than 100.

19) The Next Error/Previous Error tooltip text
messages were updated to correctly describe their functions.

20) Opening a file from the MRU when there was no child window
present did not go directly to edit mode. This has been fixed.

21) The print program function has been repaired to properly
handle large files, and selected text.

22) Cutting and pasting a line with a bookmark, no longer causes an
application error.

23) Dropping a file onto the HTBasic.exe or on to a shortcut to
HTBasic.exe for opening files is now supported. Also dropping a
file onto the open editor opens the file into the editor. Dropping
a PROG file onto an open output window opens and runs the program.

24) It is now impossible to close HTBasic while it is saving a
program. The cursor will remain a wait cursor throughout all
saving/storing, and opening operations.

25) Previously if PEN 0 had been modified, the automatic color
inverting for DUMP GRAPHICS would not take place.

26) The proper error message is now displayed when a line length
exceeds the 256 character limit. Previously this would cause an
application error.

27) Using the F1 key for help access now properly leaves the cursor
on the same line in the editor while accessing the help window.

28) Access to user defined help is now properly permitted.

29) Entering a non-existent program name in the file open dialog box
no longer causes an application error.

30) Subs may now be deleted by highlighting them. If there are
comments after the sub, they must be also included in the selection.
Previously it was only possible to delete subs in this way if there
were no comments surrounding the sub.

31) After performing a GLOAD to the screen, a DUMP GRAPHICS would
produce a solid black output. This has been repaired to properly
DUMP GRAPHICS of GLOADed screens.

32) GESCAPE CRT,52 would remove the status bar when locking the
HTBasic frame. It now only locks the frame.

33) The set indent Dialog box now properly keeps track of Default vs.
User Specify mode.

**Drivers**

1) New drivers include:

SERIAL û Support for GUI control of the SERIAL bus.
TABLET - Support for use of GRAPHICS INPUT IS Isc,"TABLET"
GPIO600 - Support for the TransEra Model 600 GPIO card
GPIO650 - Support for the TransEra Model 650 GPIO card
NOTE: Under Windows 2000 interrupts are not yet supported with
either of the new GPIO drivers.

2) Using the SERIAL device, it is now possible to load any COM
port. Previously this was limited to COM1 - COM9. Also, it is
now possible to load as many ports as ISC's available.

3) The ON INTR functionality added to the SERIAL32 driver
caused it to dramatically increase processor demand. This has been
repaired so the driver only accesses the processor as needed.

4) The READIO & WRITEIO registers for the SERIAL32 driver
have been clarified.

5) SERIAL32 driver was updated to allow Ctrl+Break or Clear I/O
in all situations.

6) GPIB driver updated to properly detect device interrupts.

7) The SICL I/O Libraries included for using the TransEra Model
900 GPIB card under Windows NT & 2000 with the HPIBS driver
have been updated to Agilent's revision J.02.02.

8) Hardware timeouts with the GPIBNI driver were incorrectly
returning error 150 when there was a device powered on or connected
to the card. This now properly returns error 168.

9) GPIBNI driver updated for faster PASS CONTROL with some NI
compatible GPIB cards.

10) GPIBNI driver updated to properly use the USING % and ûK
IMAGE specifiers.

11) PLOTTER IS HPGL updated to account for an obscure rounding
problem.

12) DUMP GRAPHICS via the GIF driver now properly inverts the
background color after PEN 0 is modified.

13) The following control register has been added to the WIN-
PRINT driver allowing the underline option in printed output:

      CONTROL 10,116;4   ! Underline
      CONTROL 10,116;5   ! Underline Italic
      CONTROL 10,116;6   ! Bold Underline
      CONTROL 10,116;7   ! Bold Italic Underline

14) The PS driver has been updated to support GFONT information
on labels. The driver supports the following fonts:

Helvetica
Helvetica-Oblique
Helvetica-Bold
Helvetica-BoldOblique
Courier
Courier-Oblique
Courier-Bold
Courier-BoldOblique
Times-Roman
Times-Italic
Times-Bold
Times-BoldItalic


**Internal Operation**

1) LONG variables are now supported in FOR loops and all ENTER
statements.

2) It is now possible to initialize a variable when it is declared.
 i.e. INTEGER I=13

3) STATIC variables now support Complex number declaration
during initialization.

4) Variables not specifically declared and set to values larger
than 65535 now evaluate properly as REAL or LONG variables.

5) XREF now differentiates array variables from standard variables.

6) Invoking HELP with three keywords generated a syntax error.
This has been fixed.

7) The CAPS LOCK status, STATUS (KBD,0) now properly reports
the state of the CAPS LOCK key.

8) The CAT command no longer shows an extra file in its listing
if a temporary file is in the directory.

9) Using the CAT command with spaces in the command now
properly CATalogs the specified directory.

10) CONFIGURE LONGCATDATES has been added as an option to
control how many digits of the year are displayed in a CAT.
Previously four digits would be displayed if LONGFILENAMES
was on. Using CONFIGURE LONGCATDATES ON, or the Run
Environment option produces a four-digit year. CONFIGURE
LONGCATDATES OFF produces only a two-digit year.

11) TRANSFER from a file to a buffer was repaired to properly
accept the ON END option.

12) TRANSFER no longer hangs if data transferred from a file is
smaller than the receiving buffer.

13) Inbound TRANSFER was not terminating when an EOI signal
was sent from the source. This has been repaired to properly detect
the EOI signal.

14) Using RETURN 1 from MAIN now properly reports an error.
Previously this would cause an application error.

15) Font information passed to the application using the ûfn switch is
only written to the registry if the Editor Environment font dialog is
updated.

16) When working with KBD CMODE on, ALPHA PEN now properly
updates the softkey colors.

17) The Alpha line height command, CONTROL CRT,13 has been
updated to work in all situations. Previously inaccurate results were
shown when working with a small alpha height.

18) Using CHR$(129) for inverse video now does not effect the
softkey line. Previously this would cause improper colors to appear
in the region to the right and below the softkeys.

19) Using LOADSUB to LOAD a String Function from an older PROG
type is now fully supported.

20) Colors now map properly in color map mode when using a
GFONT.

21) Improper assignment of LONG variables now properly produces error
19, Improper value or out of range.

22) The ENTER command has been expanded to properly handle
ENTERing into LONG variables.

23) An extra pixel was being displayed when HTBasic was idle and the
TRACK CRT cross-hair was under the mouse pointer. This has been repaired.

24) It is again possible to scroll through displayed graphics and text
while HTBasic is at a WAIT.

25) SET TIMEDATE TIME was updated to properly interact with the automatic
updating of time based upon daylight savings time. Previously this would
be off by one hour while not in daylight savings if Windows was set to
automatically update time based upon daylight savings.

**Debugger**

1) Breakpoint dialogs now remember their last settings. Variable
entry is set to top of list.

2) The calling line number has been added to the Call Stack debug
window.

3) When in Debug Paused state, clicking on Debug Run no longer stops
at line 10. It properly runs through to the first breakpoint.

4) When attempting to edit the program while paused in the debugger
now properly stops debug first.

5) During Debug, the status bar now reports the status as either
Debug Paused, or Debug Running.

6) The order of the listboxes for Breakpoints dialogs have been
changed to first list the sub and then the variable.

7) While running the debugger, the runlight now indicates either
debug run, or debug paused.


**Basic Plus**

1) BPLUS has been updated to allow focus control between Widgets
and the main Basic window. Using the FOCUS attribute it is
possible to change focus to a particular widget or to the Basic
window. A value of 0 gives focus to the specified widget, a value of
1 moves focus from the Widget to the Basic window.

2) Basic PLUS has been updated so TAB stops no longer access
Widget labels.

3) The filedialog has been updated to properly allow Screen Builder
modification.

4) With Basic Plus loaded, there is no longer a performance hit when
using SET PEN commands.

5) Corrected a problem under Windows 95 when closing HTBasic after
using Basic Plus



**DLL Toolkit**

1) The DLL Loader now supports array elements in the parameter
list. Previously it was only possible to pass the entire array.

2) It is now possible to pass Basic specific strings such as KBD$ and
ERRM$ to a dll via the DLL toolkit.

3) The ability to output to either the DISP or Message line with the
HTBDisp Dll has been added.

4) The HTBFileopen dll was enhanced to allow for multiple file
selection. It was also modified to ensure that it will always appear
in the foreground each time it is called.

5) The HTBasicrevenge dll has been updated to work properly on
800x600 resolution screens.

6) The HTBLinechart dll sample has been updated to better illustrate
its capabilities.

7) DLLs made into CSUBs using the CSUB toolkit that used non system
modal message boxes could appear behind the Basic window. To ensure
they appear in front of the Basic window, the CSUB will need to be
re-compiled with the following code which provides the Messagebox
function with a handle to the parent window.

HWND GetHandle()
{    HANDLE hBasic = LoadLibrary("htbwin.exe");
    HWND * phBasicWnd = (HWND *)GetProcAddress(hBasic,"g_hBasicFrameWindow");
    return(*phBasicWnd);
}

8) The HTBLink DLL sample was updated to prevent problems when exiting the Client
sample program.

Repairs made to 8.1 for 8.2
_______________________________________________________

1) The following GESCAPE codes were added:

    GESCAPE CRT,51 ! turns the menu bar on
    GESCAPE CRT,64 ! turns the filename in the titlebar on
    GESCAPE CRT,65 ! turns the filename in the titlebar off

2) The INPUT command was adjusted to support LONG
INTEGERS.

3) CONTROL KBD,14;X Would set the base softkey number, but it
would revert back to default if softkeys were cycled. This was
fixed to work as follows:
    0 - Lowest softkey will be softkey 1 (default),
    1 - Lowest softkey will be softkey 0. This register has
            no affect with KBD CMODE ON.

4) DEL in legacy editor would cause GPF if it deleted across
contexts.

5) Multiple control registers will now properly fill an array.
Previously in some cases this would cause the stack to be off
resulting in a "Basic Bad Stack" error.

6) Using the USER KEYS command to change to an already present
USER KEYS definition would cause the softkeys to unnecessarily
update. This has been repaired so there is no flicker.

7) SEPARATE ALPHA FROM GRAPHICS mode would not
default to MERGE ALPHA WITH GRAPHICS when closing the
child window. This would cause a GPF upon opening a new
program. This has been repaired to properly be in MERGE ALPHA
WITH GRAPHICS mode at startup despite its state at close.

8) Pasting sample programs from the help files would give erroneous
errors on lines with multiple spaces. The extra characters in the
spaces have been removed.

9) Closing the child window while waiting on an INPUT statement
would cause a GPF upon opening another program. This has been
resolved so closing the child window no longer has this adverse
effect if waiting on an INPUT.

10) Error message on cancel from Password dialog box has been
removed.

11) Under Windows 95/98 the EXECUTE command for DOS
commands was not functional. Using EXECUTE to run a DOS
command would result in a "Too Many parameters" error. This has
been corrected so the EXECUTE command will run both Windows
programs and DOS commands.


12) The control register that extends the functionality of the
SUSPEND INTERACTIVE command now properly follows the
following guidelines:

    CONTROL KBD,7;x - Disable Keyboard Interrupts:
    where x =
    0    Enable all keyboard keys.
    1    Disable all keyboard keys but RESET key.
    2    Disable RESET key only.
    3    Disable all keyboard keys.


13) SYSTEM$ ("SERIAL NUMBER") was not finding the serial
number entered during installation. This has been repaired so that
the serial number is properly returned.

14) The MODULO command has been repaired to properly
determine variable dimensions. Previously it would report erroneous
dimension conditions.

15) The SELECT statement has been updated to properly evaluate
LONG variables that were created from strings using the VAL
statement. Previously this was unsupported.

16) EXECUTE command WAIT OFF option corrected.

17) The -fn startup switch now passes in font information, including
code page selection to the Windows Editor. Note that changing the
Editor font using the Editor Environment dialog box will override
any -fn switch settings.

18) Code page selection now affects Find & Replace dialog boxes.

19) -geometry startup switch now correctly sets child window area
despite the presence or lack of toolbars.

20) Softkeys F9 & F10 under KBD CMODE ON are now fully functional.

21) When using CONTROL 10,114;2 to programmatically change
paper rotation to landscape, the margins were not being adjusted.
The margins are now properly being set to Landscape margins.

22) A scrollbar was added to the Recall bar in the Windows editor.

23) Conditional breakpoints had difficulties when using keywords as
variables. Case was not enough to separate the keyword from the
variable in the debugger. This has been repaired to allow keywords
as variables so long as the case of the variable did not conflict
with the keyword.

24) The find and find next features did not parse when used to move
from one line to the next. This has been repaired so that moving
from a line using find and find next has the same effect as moving
the cursor off the line.

25) Using ISC 26 to print, DUMP, and then print again on the same
paper is now supported. Using CONTROL 26,112;x and CONTROL
26,113;x to control the auto eject after printing and DUMPing is now
fully supported. Previously this was only supported when using
WIN-DUMP, and WIN-PRINT.

26) When using a Bold large font in the new editor under the
Windows 95/98 operating systems, the text would appear to jump
when placing the cursor between characters. The character sizes are
now being updated properly so there is no apparent jump.

27) When using the Print Program feature found on the File menu, the
page indication at the bottom of the printed page would sometimes
be cut off. This has been repaired so the page indicator is complete.

28) CONTROL PRT registers 109 & 110 were implemented to
provide the ability to specify X and Y coordinates with the WIN-
PRINT driver.

29) The APPEND option for DUMP DEVICE IS 10 now behaves as
CONTROL PRT register 113 for DUMP GRAPHICS page eject
control.

30) HPGL plotter driver was ejecting an extra blank page after each
plot. This has been repaired to no longer eject the extra page.

31) ENABLE INTR was not releasing memory once it was
complete. This has been resolved so that memory is no longer
reserved.

32) ON INTR on the serial bus would not report interrupts after an
END statement was processed. This has been repaired to function
properly.

33) The GPIBNI driver was updated to handle all TIMEOUTs as
software timeouts. The resolution of these timeouts is now from that
of the Operating System's limit to 32.767 seconds. For Windows
95/98 the resolution is 55ms, for Windows NT & 2000 it is 10 ms.

34) Basic Plus updated to improve event handling.

35) Basic Plus binary updated to handle SCRATCH ALL situations.


Repairs made to 8.0 for 8.1
_______________________________________________________

1) Occasionally a password would mysteriously appear in a PROG
file when the save with password option was not checked. This was a
problem when checking for the presence of a password on the file.
There was no password on the file. This has been corrected to read
properly.

2) The CONFIGURE MSI command would only allow 80
characters. This has been increased to handle 256 characters.

3) A new command: CONFIGURE SYSTEM
"HPBDAT;READEOF" was added for proper reading of BDAT files
with HP style headers.  The default setting is to report an error on
EOF rather than to read the contents of the file. The default behavior
is to disable reading of the file. This option may be placed back to
the default using: CONFIGURE SYSTEM "HPBDAT"

4) The VIEWPORT command was not properly aligning with the
RATIO command during a PLOTTER IS statement. This could cause
some plots to appear in an unexpected location. This required a
second PLOTTER IS statement. This has been repaired so the
VIEWPORT command is now properly aligned during a PLOTTER
IS statement.

5) The -geometry switch was ignored if HTBasic was closed while
maximized. This was corrected so the -geometry switch is used no
matter what the screen position or size was at last close of the
application.

6) The -geometry switch was not recognizing the Y Offset
parameter. This has been corrected so that the application now starts
in the correct position as specified with the -geometry switch.

7) The Device Setup Dialog box was too large for screen resolutions
less than 640X480. The dialog box was made smaller to fit into this
screen resolution.

8) Device setup dialog box would allow text input for ISC. This
information was not read and would cause unpredictable errors in
ISC assignments. This was repaired to only allow dropdown list
selection for the ISC.

9) The Device setup dialog box would cause a GPF if devices were
added in HTBasic using LOAD BIN statements if there was no
printer installed in the system. This has been corrected so any device
may be added to the system without first having a printer installed.

10) The command RE-STORE KEY would improperly give the
updating prog format dialog box when restoring current softkey
definitions. This has been repaired to STORE the keys without the
prompt.

11) ON TIMEOUT support was added to the Serial driver during
TRANSFERs.

12) ON TIMEOUT support for software timeouts was added to the
HPIBS driver. Previously only hardware timeouts were functional.

13) Improvements were made to the Global breakpoints handling in
the Debugger.

14) The INMEM command was enhanced to properly report Loaded
DLLS.

15) Setting buffer CONTROL registers in one line was not
functional. This was repaired to allow proper setting of multiple
buffer related CONTROL registers on one line.

16) The command line switch -fn, used to change the display font
was affecting the -geometry switch that specified the number of
characters to display. This has been fixed so that a geometry switch
that is less than 100 will properly set the window size to reflect an
alternate font's size.

18) The context sensitive help accessed by hitting the F1 key with
the cursor positioned on a keyword was only functional when the
MSI was the same as htbwin.exe. This was corrected so context
sensitive help is functional despite the MSI setting.

19) Keywords were not properly colored in the Windows editor if
they were preceded by a minus sign. This has been repaired so the
minus sign has no effect on adjacent keyword coloring.

20) Control KBD,0;X now properly turns on and off the Caps Lock.
Previously both a value of 1 and 0 would only toggle the Caps Lock
State. A 1 will now turn on Caps Lock, and a 0 value for x will turn
off the Caps Lock.

21) The CONFIGURE SYSTEM command has been enhanced to
allow up to 256 characters in the PC path specifier.

22) A correction was made to the SERIAL32 driver to resolve some
timing issues with ON INTR. These issues were discovered with
tight OUTPUT and ENTER communication as in loopback testing.

23) Support for MAT commands on LONG arrays has been added.

24) CAT SELECT of a file with an extension, or a directory would
not display if just the first half of the file name or directory
name was given. This has been repaired to properly give the correct
SELECTed file results.

25) GFONTed LABEL characters were not properly affected by the
CLIP and LDIR statements. This was corrected so the CLIP and
LDIR statements properly affects all LABEL statements, including
GFONT changed LABEL statements.

26) When a string was entered using the GPIBNI driver with
ENTER USING "%,-K";A$, the LEN(A$) would report the string
dimension rather than the string length. The driver has been
updated to correct this.


Basic Plus
_______________________________________________________

Some changes regarding the effects of HTBasic Plus on HTBasic
Graphics were made. The details of this interaction follow:

There are two HTBasic Plus graphic modes that are supported.
Standard and ReadOnly. The ReadOnly mode is selected with the û
cu ReadOnly command line switch, otherwise the Standard mode is
used.  The effects of each of these modes is explained below.

While HTBasic Plus is loaded, HTBasic for Windows graphics will
be placed in the color map mode (i.e., PLOTTER IS
CRT,"INTERNAL";COLOR MAP) if your computer's display
system supports it.  This implies that all PLOTTER IS
CRT,"INTERNAL" requests will be converted.

Standard Mode:

Standard Mode supports two separate color maps. One for HTBasic
and the other for HTBasic Plus. After each of the following events...

  LOAD BIN "BPLUS"
  MERGE ALPHA WITH GRAPHICS
  PLOTTER IS CRT
  GINIT
  RESET
  SCRATCH A

HTBasic Plus will initialize the HTBasic Plus color map to the
values specified in your CONFIG file (see "Customizing Pens").
Which portion depends on two things:

  1. How many colors are available to HTBasic for Windows as
specified with the "-colors" HTBasic for Windows command line
switch).

  2. Which HTBasic for Windows pens are referenced in the logical
pen portion of your CONFIG file.

By default, HTBasic Plus uses 16 colors.  If less than 256 colors are
available to HTBasic for Windows, these 16 colors are mapped to
pens 0-15 and pens 0-7 are set the same as the HTBasic for Windows
default. If 256 colors are available, the 16 default HTBasic for
Windows colors are mapped to pens 16-31 in the HTBasic Plus color
map.

The SET PEN command does not affect the HTBasic Plus color
map.  The color map may only be changed from within the CONFIG
file.

-cu ReadOnly mode:

In ReadOnly mode both HTBasic for Windows and HTBasic Plus
share the same color map. After each of the following events...

  LOAD BIN "BPLUS"
  MERGE ALPHA WITH GRAPHICS
  PLOTTER IS CRT
  GINIT
  RESET
  SCRATCH A

HTBasic Plus will re-map or translate a portion of the HTBasic for
Windows color map to the values specified in your CONFIG file
(see "Customizing Pens"). Which portion depends on two things:

  1. How many colors are available to HTBasic for Windows as
specified with the "-colors" HTBasic for Windows command line
switch).

  2. Which HTBasic for Windows pens are referenced in the logical
pen portion of your CONFIG file.

By default, HTBasic Plus uses 16 colors.  If less than 256 colors are
available to HTBasic for Windows, these 16 colors are mapped to
pens 0-15 and pens 0-7 are set the same as the HTBasic for Windows
default. If 256 colors are available, the 16 default HTBasic for
Windows colors are mapped to pens 16-31.

If you subsequently execute any SET PEN command, that definition
remains in effect until any of the following events occur:

  MERGE ALPHA WITH GRAPHICS
  PLOTTER IS CRT
  GINIT
  RESET
  SCRATCH A

However, because of the mapping, mapped pens are no longer
affected by their original pen number.  By default, pens 16-31, 230,
231, and 238 are mapped to different pen numbers.  For example,
pen 18 is mapped to pen 2's color.  A SET PEN 18 command will
not change pen 18's color. However, a SET PEN 2 will change any
pen 18's that have already been written to the HTBasic screen, but
will always be the original color at the time it is written.
Because of unpredictable results, it is not recommended using the
SET PEN command with the ûcu ReadOnly mode.


Repairs made to 7.3 for 7.4
_______________________________________________________

1) DEL in legacy editor would cause a GPF (General Protection
Fault) if it deleted across contexts.


Repairs made to 7.2 for 7.3
_______________________________________________________

1) Unassigned Softkeys would cause program hang. This has been
repaired so undefined softkeys do not hang.
