Using exec in the Window environment

[rajprakash]

I am a new user of the tcl . I am currently planning to use exec to create a subprocess like a worker to process the background work.
I am having problem with exec getting to work. Here is my question:
exec tcl-command
Would this work? In other words, let us say that I use date /T as example. THis did not work just the way I have it.
Also if I want to exec another tcl program that I created, how do I exec it?

Pleas help.....

As far as i know (by using this call from Cobol), you can't execute internal DOS commands, just external .COM .EXE and .BAT (only in WinXP) files.
To execute internal DOS commands you must use the Comspec system variable and call the "DOS commander" (command.com, cmd.exe etc) with the /C switch.
Also don't forget to nul-terminate the command string you pass to the EXEC call, as Windows workes like C...
Hope i helped a little.
