The environment space on DOS 3.2 may be set in the CONFIG.SYS file by specifying SHELL=COMMAND.COM/E:xxxx where xxxx represents the bytes of environment space as a decimal integer in the range of 160 to 32768. I'm taking this right out of the PC DOS 3.2 reference manual (page 4-34). PC Magazine had a discussion of this a few months ago in their PRODUCTIVITY section in the back. The /e: option on the shell command works for DOS 3.1, too, but it indicates a number of blocks of environment space rather than the number of bytes. I forget the block size, but I think it was on the order of magnitude of 100 bytes/block.

The COMMAND.COM option /E: in DOS 3.1 and earlier expects values in paragraphs, which are 16 bytes each. As said earlier, DOS 3.2 and later expect values in bytes. The defaults are: DOS 3.1 & earlier DOS 3.2 & later /E:10 /E:160 reserves 160 bytes reserves 160 bytes

Nope, its 16 bytes/block, also known as a paragraph.

In MS-DOS 3.1 the argument after the e: option specifies the number of paragraphs (16 bytes each) of environment space. This was never documented for MS-DOS 3.1, so there may be cases where it can't be trusted. However, I use it reliably on AT&T's MS-DOS 3.1 for the 6300, and I also use it with a generic MS-DOS 3.1 on a IBM XT-clone. I think the maximum environment size that can be specified for MS-DOS 3.1 is 64 paragraphs, or about 1024 bytes. -- Dave Levenson Westmark, Inc. A node for news.
