Hi Mike,
Have another look at the help message for system exec.vi. You'll see that there is an input for "Standard Input" That's where to put the Tcl commands - I think I said that last time.
The "wait until completed" (in this example) affects whether or not you will be able to communicate with your shell in an MS-DOS window or not [I am guessing that the Tcl shell uses an MS-DOS window for its I/O, rather than making its own] This gives you the choice of an interactive session with your shell, or loading a series of commands into the vi's "Standard input" and having the results appear in "standard output"
The "run minimised" option determines whether or not you see the MS-DOS window. If you want an interactive session you'll want this to be false!
I don't have tclsh, so can't be sure how it will behave, but the technique works fine for another program that is called from MS-DOS, such as ftp.
Rod.
