PB 3.5 shell collapse using PKZIP

[Barry Erick]

Mel -
I have no problem running PB for dos with Win98 in a window or
a full screen mode. I still do checks on any bug reports for
my various DOS programs under win 98.

Thank you Lance.

The debugging stuff is exactly what I am going through now. Of
course the permutations and combinations are 1 in 10 to the n-1
possibilities. It's a air number of miles back and forth to
experiment. If the DMPI game isn't where it is at with -), then
I'm considering writing a command line toggle to try the rest,
with conditional execution prompted from outside the program.

I really want to keep the utility. In practice, a 20MB archive
of what is involved with PKZIP mushrooms into abou a 28MB archive
with Info-Zip's tool. Doesn't sound like much, but at 28800 on
some phone lines daily, that's a lot of time wasted day after
day after day..

Tnx ..

Years ago I saw a similar problem with "buggy" versions of NW-DOS 7. The answer at the time was to disable DPMI, etc.

Try using some of the following PKZIP command-line switches:

-3      Disable 32-bit instruction usage on 80386 or higher CPU's
-^      Echo the command line
-+      Disable Expanded Memory (EMS) usage
--      Disable UMB/HMA Memory (XMS) usage
-~      Disable Network usage
-)      Disable 32 bit DPMI usage
-(      Use "Slow" MemCopy

I have a similar problem with Win98 trying to run PB for DOS.
In a DOS window, in two words, "it don't". I THINK it has to
do with 98's memory management or something similar. The only
way I have been able to "fix" the problem is to F-8 and go with
a pure DOS prompt. Most of the time, this works but on
occasion....

If you run across a solution, please let me know. Sorry I don't
have an answer for you but thought you would like to know you
are not alone.

I've been using PB 3.5's Shell with the Ultrashell utility for a
long time now and have never had a problem until this one.

On WIN98 only, I hit an exception code error as PKZIP version 2.5,
I think it is actually 2.504, appears to want to write output to
the disk. PKZIP has never been used as a Shell-Child in anything I
have done before, and this never showed up in DOS-VDM's in OS/2,
nor in pure DOS boxes.

It is not, one would think, a PB problem, nor, would I think from
Ultrashell. Nor have I tried substituting Info-Zip's tools, which
I will try also.

I've tried resetting the memory sizes and switches in the WIN-98
session properties box. There is plenty of memory there and nothing
tried has been able to break the abend.

Anyone got any thoughts?
