While we're "on the subject", can anyone tell me why an EXEC from Turbo Pascal
4.0 or a SHELL from a compiled BASIC program always results in a *smaller*
environment?

Specifically, when I do either of the following:
BASIC:	SHELL("LOTUS.BAT")
Pascal:	exec('command.com','/c lotus.bat');

Where LOTUS.BAT is the following:
c:
cd\lotus2
prompt Type "EXIT" and press RETURN to return to Lotus 1-2-3$_$p$g
lotus
prompt $p$g
c:
cd\

I get an "Out of environment space" msg when the bat file runs. Using the
/S option in Lotus (2.01) gets a prompt that ends at the 't' in 'return'.

But if I run the same bat file from DOS it works....
And no matter *how* much environment space I setup it still happens if I
run it as a child process. I get the impression that DOS only passes along
the environment variables and a paragraph or so of 'extra' environment space?!
