Forum OpenACS Q&A: Response to Breaking lines in Tcl files

I have experienced the same problem several times when trying to continue a tcl command onto additional lines by using the backslash character at the end of the line.  On those occasions, I double-checked that there was nothing following the backslash, tried terminating the line with Ctrl-J and newline in emacs, did some other tinkering, and then gave up and put everything on one very long line.  I wonder if there are some circumstances where the continuation convention will not work.
