Grunt.  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.
