Thanks for the response. I don't understand why, but commenting out the
above line and restarting emacs doesn't change the behavior. (I do not
have a rexx-mode.elc. If I start emacs with --no-init-file, rexx-mode is
not recognized.)
Backslash is never an escape in Rexx. Rexx allows either single or double
quotes to delimit a string, so '"' would be a double quote. A string
containing both kinds of quote could be built by concatenation.
