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.
