    Your (Rex's) reply:

    I'm still completely inexperienced with TCC (versus 4NT, which I used since the Neolithic): I read the documentation for BREAKPOINT and found that the debugger has to be running for the command to work. So I ran it, then put a BREAKPOINT statement into a .btm file, then ran the .btm file from the TCC command line.

    I assumed -- incorrectly, I guess -- that this would cause the script to then appear in the BDEBUGGER window, paused at the BREAKPOINT statement. It didn't happen.

    What is the correct procedure for getting this result (if it's possible)?

    I found that running BDEBUGGER did not return control immediately to the user (at the command line); it was like using "start /wait". I tried "start bdebugger" but that opened another command shell (before launching the debugger). Is there a way to run the debugger and then immediately get control back at the same command prompt where the command was launched -- without opening a second TCC console window? That is, before BDEBUGGER exits?

    No -- the debugger is running TCC and the batch file; TCC is not invoking
    the debugger. There is no way you can invoke the debugger in the middle of
    a batch file from TCC (nor will there ever be).
