Per commentary to https://retrocomputing.stackexchange.com/a/9623/1932:

I have tried %@EXEC[] to run a BTM from my prompt in 4DOS/4OS2/4NT/Take Command/TCC, but the return value of the BTM ends up in the prompt. Can I stop that from happening? How?

There are two ways to do this. They are both in the doco.

  • Prefix the BTM with @. I have a vague memory that this was not available in some very old versions of these command interpreters.
  • Use $h to backspace over the 0. This presumes that the exit code of the script in human-readable form is always one character long, and is therefore the less preferable mechanism.
