Bad, bad, TMW! :)
Appears the shell commands under Windows don't pay any attention to what user COMSPEC is...one gets CMD.EXE irregardless...
>> !ver
Microsoft Windows [Version 6.1.7601]
>> shell=getenv('comspec')
shell =
'"C:\Program Files\JPSoft\TCMD22\tcc.exe"'
>> system(shell)
TCC 22.00.41 x64 Windows 7 [Version 6.1.7601]
...
[details elided]
...
C:\DBNonBusiness...paign\Financials> exit
ans =
0
>>
This makes using features of an enhanced command processor much more of pain than otherwise and is a kick in the teeth, particularly with the restrictions TMW has placed on wildcards, etc., in their implementation of dir, etc., etc., ... I've been stewing over this for 20 years and today was finally the boiling over point to complain... :)

Having never had an installation of Matlab on a unix boxen; out of curiosity what happens there regarding which shell; does TMW make some arbitrary choice there, too?

"MATLAB uses a shell program to execute the given command. It determines which shell program to use by checking environment variables on your system. MATLAB first checks the MATLAB_SHELL variable, and if either empty or not defined, then checks SHELL. If SHELL is also empty or not defined, MATLAB uses /bin/sh."

Thanks, Walter...as one would expect, unfortunately, setting either of those doesn't effect Windows.
At the moment I don't have a supported compiler installed other than the default C compiler and I'm so inept in C hate to even make the attempt at a .mex file...is there any "backdoor" to Win API to bypass the builtin DOS.M to spawn the shell, you think?
Mayhaps this is a Q? for Yair to ponder... :)

I was really unaware of it, we can access cmd using Matlab. Thanks.
.m files can be combined with anything. :) .
And Bro why you replaced CMD.exe mean upgraded to ("TCMD22\tcc.exe")?
