BCAST SOFTWARE PACKAGE REVISION LOG RECORD
-----------------------------------------------------------------------------
BCAST SOFTWARE PACKAGE REVISION 1.02 (30 July 1992):
KGRAPH = Version 1.01 { Upgraded }
BCAST = Version 1.02 { Upgraded }
MISSING = Version 1.01 { Upgraded }
FIELDS = Version 1.01 { Upgraded }
AVG = Version 1.00 { New }
UPDATEK = Version 1.00 { New }
- Changed date formats from MM,DD,YY to YY,MM,DD to help standardize the
date formats with the archived filename formats.
- Fixed minor problem to load new batch of data after processing new
dataset(s) in BCAST.
- Added the ability within the KGRAPH high-density geomagnetic data
plots to shift the screen 14-days to the left to view days which were
truncated and/or to aid in analyzing approaching recurrent patterns in
magnetic activity. [KGRAPH is now at Version 1.01].
- Fixed problem which prevented the cursor from scrolling properly when
maneuvering within the file-selection screen of BCAST for processing
new datasets.
- Fixed bug associated with deleting datasets while working in
directories where the database file does not exist.
- KGRAPH can now be run from any directory provided the "BCAST"
environment variable points to the directory containing KGRAPH (see
the manual for more information).
- The high resolution plot of geomagnetic activity in KGRAPH will now
support the option of graphing 27 or 28 day cycles. Press "7" to
graph with 27-day cycles and "8" to graph with 28-day cycles to aid in
isolating and aligning periods of recurrent activity.
- Fixed minor bug to permit case-independent acronyms in the
initialization file (BCAST.INI).
- Added additional permissible acronyms to the BCAST initialization file
(BCAST.INI) to permit setting preferred defaults to the KGRAPH
utility. See the BCAST manual (BCAST.MAN) and/or BCAST.INI for more
information regarding the new acronyms.
- Added ability to save VGA graphics screens in KGRAPH to a GIF image
file and/or a Postscript compatible file for printing on a laser
printer. Save screens to GIF files by pressing "G" (for GIF) and save
to Postscript files by pressing "P" (for Postscript) while viewing VGA
screens in KGRAPH. Screens can be saved in several different formats
for printing on two-color printers (ex. dot-matrix). Defaults are
defined using new acronyms in the BCAST.INI initialization file.
- The utility program MISSING can now be used from any directory,
provided the BCAST environment variable points to the directory
containing the database file "datasets.dat". [MISSING is now at
version 1.01].
- MISSING now reports the dates of the first and last datasets stored in
the database file.
- The utility program FIELDS can now be used from any directory,
provided the BCAST environment variable points to the directory
containing the database file "datasets.dat". By default, FIELDS
searches the current directory for the format specification file
"format.fmt" (not the directory given by the BCAST environment
variable). [FIELDS is now at version 1.01].
- Patched BCAST to properly scale graphs when missing data exists.
- Added completely new utility program to compile extensive reports
based on numerical averages calculated from the BCAST database file.
Can compute fixed or running averages for any number of days. The
utility filename is "AVG.EXE". Consult the users manual ("AVG.MAN")
for more information. [AVG is now at version 1.00].
- Added new feature to KGRAPH. When viewing the high-density
geomagnetic K-index data, you can force KGRAPH to replace the dates
with the appropriate A-indices by pressing the "A" (for "A"-Indices)
key. This key acts as a toggle. You can therefore restore the dates
by pressing "A" a second time. You can force KGRAPH to display the
A-indices as the default by modifying the BCAST.INI initialization
file to include the acronym "AINDEX-SHOW". See the KGRAPH.MAN users
manual for more information regarding the new acronyms.
- Added additional acceptable WARNINGS acronyms to BCAST, as follows:
"FORBUSH" - Potential Forbush Decrease Warning
"SWF" - Potential HF Radio Short Wave Fadeout Warning
"MAGPAUSE" - Potential Geosynchronous Magnetopause Crossing
Warning
- Added additional acceptable ALERTS acronyms to BCAST, as follows:
"PROEN100" - Proton Enhancement Alert at > 100 MeV
"MAGPAUSE" - Geosynchronous Satellite Magnetopause Crossing
Alert
- Added completely new utility program "UPDATEK" to the BCAST software
package. This program automatically updates all of the planetary
geomagnetic A and K indices to more accurate (corrected semi-final)
values based on the values that were observed 27 days ago. [UPDATEK
is now at version 1.00].
-----------------------------------------------------------------------------
BCAST SOFTWARE PACKAGE REVISION 1.01 (12 February 1992):
- Fixed minor bug which occurred when attempting to batch process
non-existant files.
- Completely rewrote the "Process Data Set" section of the main menu to
provide powerful dynamic file-selection/processing features.
- Enhanced the menu selection procedure to permit fast single-keystroke
operation within the menus.
- Tweaked appearance of menus and added on-screen version information.
- Added PAGEUP, PAGEDOWN, HOME, and END keyboard support functions while
viewing graphical charts to permit dynamic movement and analysis
within the database.
- Modified the "Delete Dataset" function to permit the deletion of
datasets containing illegal dates. May be useful to help repair
corrupt datasets within the database.
- Added support for an external configuration file, to permit minor
customization of the BCAST software and a base structure for future
customization features.
- Added support for the environment variable "BCAST". Specifically, if
the variable BCAST is set to the directory path of the BCAST software,
you may execute and operate BCAST from any directory on your system.
- Optimized program code to help reduce executable program size. All of
the above features have been added while reducing the overall program
size by over 5K bytes.
-----------------------------------------------------------------------------
BCAST SOFTWARE RELEASE 1.00 (18 Nov 1991):
- First release. No major bugs reported.
