You can increase the environment size in dos 3.x by specifiying the
start-up shell in your CONFIG.SYS file.  Normally, you'd want
COMMAND.COM to be the shell.  I've seen a lot of errors in owner's
manuals regading the options for the SHELL= parameter.  Many
manuals say that enviornment size is specified in bytes; this is
only true for DOS 3.2 and 3.3.  3.0 and 3.1 measure the environment
size in 16 byte paragraphs.  Under 3.0 and 3.1, divide your desired
environment size by 16 to get the number to be used for the
parameter.

Use the following syntax for the CONFIG.SYS entry:

	SHELL = C:\COMMAND.COM /E:1024 /P

The /E: specifies the environment size. /P means "permanent", and
has to be present.  The /P indicates to COMMAND.COM that it is the
inital program, and it is OK to mess with the envrionment size; I
think it also means that this is the shell that will be reloaded
when a program dumps command.com to get extra space.

DOS 2.x requires patching to increase environment space.  That's a
good enough reson for me to suggest dropping 2.x, unless you have
an older program you need to run that gorks on 3.x.
