- Using PKARC 2.0 with a DOS environment larger than 236 bytes may cause
- PKARC to abort with an "Insufficient Memory" error. This problem
- can be fixed as follows.
-
- Using debug, change the byte at offset 417D hex in the file PKARC.COM,
- version 2.0, dated 12-15-86. The value in the distribution copy is 8.
- Changing this value will yield the results shown:
-
- Byte at 417D Maximum environment size
- ------------ ------------------------
-
- 8 236 bytes
- 7 492 bytes
- 6 748 bytes
- 5 1004 bytes
- 4 1260 bytes
-
- A value of 6 should be sufficient for most situations. Using a value
- less than 4 may cause unpredictable program operation and is therefore
- NOT recommended.
-
- The following example session with debug will change the value to 6:
-
- Enter
-
- debug pkarc.com<CR>
-
- where <CR> means the enter key. Debug will display a "-" prompt. Then enter
-
- e417d<CR>.
-
- Debug will display something like "xxxx:417d 08.". The xxxx value will
- vary from computer to computer. Debug should display the number 08 as
- above. If this value is not 08, then you do not have PKARC 2.0 and
- should not continue. This patch is only necessary for PKARC 2.0.
- Enter
-
- 6<CR>
-
- followed by
-
- w<CR>
-
- and then
-
- q<CR>.
-
-
- The result should appear similar to:
-
- A>debug pkarc.com
- -e417d
- xxxx:417d 08.6
- -w
- -q
- A>
