I was wondering if anybody out there new What I need to do to change the size of my DOS environment? I have an IBM AT running DOS 3.1. Thanks! Manuel

I have an IBM AT running DOS 3.1. DOS 3.1 doesn't have the /E switch available for resetting the size of the environment space via the 'shell =' command in CONFIG.SYS (as you have probably discovered.) The only options I know are: 1) Get DOS 3.2 (of course, you have to install it on your hard disk, which might require unloading everything if it doesn't fit) 2) If you are using the true PC-DOS (*not* MS-DOS) 3.1, then track down a copy of the SETENV utility included with MSC 5 or MSC Fortran. This patches COMMAND.COM to increase the size of the environment space. SETENV doesn't work with DOS other than PC-DOS, at least for the ones that I have tried (Compaq, Leading Edge) -- Tom Wilson wilson@uhccux.UUCP wilson@uhccux.uhcc.Hawaii.Edu (Internet) wilson@uhccux (Bitnet)

MSDOS (maybe not PCDOS?) v3.1 supported the /E switch in a slightly different manner than v3.2 and up, and it wasn't a documented feature. The line shell=c:\command.com c:\ /e:20 in the CONFIG.SYS file should specify an environment of 20 "paragraphs", or 320 bytes. (For v3.2 the /e specifies bytes, not paragraphs.) Note that this doesn't help if your problem is a too-long PATH string; there's a limit of <127 bytes per string, regardless of the number of strings in the environment. This limit can be tricked, but it's a pain. Microsoft's various attempts at an operating system are all pains.

DOS 3.1 did have the /E switch available. PC-DOS and many MS-DOS versions didn't document it, though. The systax is not the same as that in 3.2+. The /E:nnn refers to the number of _paragraphs_ to alloc- ate to the environment; thus, /E:32 will set up a 512 byte environment. I suspect Microsoft anticipated the change and simply dropped the documen- tation from 3.1. It works in Compaq, IBM, and at least one 'generic' ver- sion I've used. Jim Borza Disclaimer? Sure, why not?
