- Update History 8-12-90
- -----------------------
-
- - Version 1.72 -
-
- Fixed again: Stored files (-lh0-) sometimes were skewed by one byte.
-
- Fixed: The extract process could get hung up if the last file in the
- archive was very small, like less than 20 bytes.
-
- Fixed: Reverse scrolling text that has lines longer than the screen width
- used to display some duplicated text.
-
- Fixed: After extracting, the default filename for the 'Show File' function
- could get messed up when the archive contained folders.
-
- - Version 1.71 -
-
- Fixed a problem with 'Show File' that could occur in low memory operation.
- 'Show File' also remembers the path that is being used.
-
- Some programs turn off the wrap-around function of GEM's screen drawing.
- This caused long lines to be cut off at the edge of the screen, so UNLZH
- now makes sure the wrap-around function is turned on.
-
- - Version 1.7 -
-
- 'Show File' function has been added to the main menu. This function enters
- the same file viewer as extract 'To Screen', but is for viewing text files
- directly from disk. Select 'Show File', then use the GEM file selector to
- enter the desired text file. The default filename gets set to the most
- recent extracted file starting with 'READ' or having the extension 'TXT',
- 'DOC', or 'ASC'. This makes it easy to view a text file that has just been
- extracted from an archive.
-
- The 'View' archive function from the main menu can now send the listing to
- a disk file. If you do select the 'Disk' button, you will get another GEM
- file selector requesting the name of a file to write the text information
- to. The listing has also been improved by adding the name of the archive
- itself. This allows you to make a nice listing of multiple archives to
- send to Disk or Printer. Select 'View', and leave the input filename set
- to '*'. The function will then create a combined listing of all of the
- archives in the directory.
-
- Within the extract 'To Screen' viewer, (including the Show File function),
- you may mark blocks of text to be sent to disk. This works in the same
- manner as sending blocks to printer, but uses the 'D' key. Move the screen
- display to the starting position you wish to save, and press 'D'. You will
- then get a GEM file selector to enter the name of the output file. Then
- move to the desired ending position, and press 'D' again. This will write
- out the text file.
-
- There have also been a few bug fixes including:
- Subdirectories created with LHarc 1.13 are extracted properly.
- Furthur improvements to handling files in low memory situations.
- Installed application works correctly again. It would fail when a
- configuration including pathnames had been saved.
-
- - Version 1.61 -
-
- UNLZH will now extract empty folders.
-
- Adjustments have been made to the 'Bad Header' search routine to prevent it
- from using additional headers in Stored archive files. It also eliminates
- Bad Header messages that could occur at the end of archives that contained
- other archive files.
-
- Fixed some problems that could occur in low memory situations, plus made
- the memory usage a bit more efficient.
-
- Blocks of text can be sent to the printer from within the extract To Screen
- function. The menu of archive contents now comes up with certain file types
- already selected. See the extract To Screen section for more information.
-
- Double-clicking is now supported from the menu of archive contents. It
- selects the file and goes directly to the extraction process. If you are
- selecting multiple files, you may use a double-click on the last one.
-
- - Version 1.5 -
-
- Extract to screen continues through multiple files correctly. View
- function now requires either 'ESC', or both mouse buttons to continue.
-
- Now supports pathname extraction from archives created with LHarc 1.01.
- For display and file selection purposes, empty pathname entries show only
- the last 13 characters, and all other entries show only the filename. In
- all cases, the full pathname will be used when saving to disk. Partial
- extractions using the w/Query mode are accepted, and will create whatever
- folders are neccessary to place the file in its designated place.
-
- Extracts self-extracting type archive files.
-
- Fixed: Uncompressed files (-lh0-) could sometimes be skewed by 1 byte.
-
- LHarc .51 does not store a CRC value for uncompressed files, therefore
- UNLZH thought it was getting CRC errors. I now do a check for this
- condition and instead report the message 'No CRC'. This means it is
- impossible to verify if these files are okay. It's unfortunate that the
- author of LHarc didn't realize that uncompressed files are just as
- susceptible to transmission/media errors as compressed files are.
-
- - Version 1.4 -
-
- Fixed: If a configuration was saved before doing any extractions, the
- program would crash the next time it was run.
-
- Extract to Screen should be properly formatted for larger display sizes.
-
- There are many new additions to the Extract to Screen function. See the
- sections on 'To Screen' and 'View' for details. The flexibility of the
- Extract to Screen, I feel, allows you to keep most of your documentation
- files in LZH archive(s), and still have easy access to their information.
