It's not really VP/ix per se, it's the presence of those TSR redirect
utilities normally loaded in a VP/ix task's AUTOEXEC.BAT initialization.
I used to have to wrestle with this under native DOS too.  

There is a COMMAND.COM switch to allocate environment space (/E:nnn,
where nnn is either bytes or paragraphs depending on the version of DOS,
thank you very much Microsoft).  In your CONFIG.SYS say

	SHELL=C:\COMMAND.COM /E:2048 /P

This is what I use with DOS 3.3 which interprets /E in bytes.

If that doesn't do the trick, you can CHEAT as follows:

*** in autoexec.bat

  set DUMMY1=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx...xxx   (100 or so)
  set DUMMY2=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx...xxx
  set DUMMY3=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx...xxx

   ... as many as will fit in the /E:nnn space you provided

Then later on just unset DUMMY1..n for more E-space.
