Permanently setting Environment Variables in DOS

[Imagineer]

I'm trying to set some environment variables in a DOS (actually WinNT 4.0 cmd) shell. I know that changing the value in the ENVIRON variable does not pass the value back to the shell. I've tried using the system() command thusly,

sVar = "EnvTest"
sValue = "oldhat"
if (system("Set " sVar "=" sValue )!= 0) #Set var and check for error.

and

if (system("Set EnvTest=oldhat&quot!=0) #Set var and check for error.

Neither statement returns an error nor do they set the variable.

Any ideas?
TIA,
Mark Imagineer

I hope I understand you correctly.

can't you set these vars in:
start
controlpanel
system
advanced
environment variables.

Then it is permanent.

Permanence is a relative thing. What I meant was that I needed them to last beyond the current session of awk. Awk allows you to read the environment variables using the ENVIRON array. The values in the ENVIRON array can be changed but they do not return these values back to the OS. All changes are lost when Awk ends. I am using the environment variables to pass values from one program to another. Imagineer
