* NOTE: If ARCID appears unable to identify some ARJ self-extracting archive,
this is not a limitation of ULP, but bugs in ARJ versions 2.21, 2.21a
and 2.22. The ARJ SFX signature was not inserted into the ARJ SFX
header, therefore no program relying on this signature (such as ARCID
and ULP) cannot detect ARJ SFXs created with these versions. Version
2.20 and 2.30+ correctly insert the signature.
1.07 - Enclosed new registration and support information. Refer to the
(12/20/94) enclosed !NOTICE! file for more information.
1.06 - Added support for signature detection of JPEG/JFIF files. Use the
(12/2/94) extension "JPG" on the ARCID command line to enable detection of
JPEG/JFIF files in your batch files, etc. that utilize ARCID.
Removed the PAK SFX detection code, as it was producing occasional
false detections of normal executables. Due to the design of PAK,
just 1 byte is used to identify a SFX which is simply too unreliable
for production use.
1.05 - On a few systems, ARCID would appear to go out to lunch during the
(2/4/94) beg screen delay. It seemed most prevalent on DESQview systems that
removed the time slices from the timer's looping, and could freeze
the system. Fixed by changing to a less CPU-intensive timing
function.
1.04 - It appears I was overzealous in my attempts to not falsely detect an
(12-4-93) ARC format archive, and was not recognizing some valid ARC archives.
Fixed.
1.03 - ARCID was unable to automatically identify PKZIP 2.04? self-
(5-9-93) extracting archives created with the -j switch (SFX junior). Fixed.
Added a sample SLOWDRV.BAT file for use in conjunction with PCBoard
version 15.0.
1.02 - The self-extracting archive detection routine could intermittently
(12-22-92) fail depending on the location of the archive signature. Fixed.
1.01 - ARCID is now capable of autmatically identifying SQZ and SQZ self-
(12-16-92) extracting archives. Just add "SQZ" (no quotes) to your ARCID
command line extension list and trap the appropriate DOS errorlevel.
The screen-clearing code has been removed for better aesthetics when
called from other programs or batch files.
Increased the scanning range, improving it's reliability for archive
identification.
1.00 - The archive identification routine has been strengthened to reduce
(9-18-92) false identifications.
Salt Air (PCBoard Support BBS) has granted me an ULP support
conference on their system. It is conference #42, and I will be
monitoring it at least twice per week. You can get support for ARCID
as well there.
0.93ß and 0.94ß - Initial beta test releases.
