subject: Goto

ML> There is no GOTO.  There is a SIGNAL, that looks and smells like a GOTO
 ML> but has _horrible_ side effects (knocks down internal structures) if
 ML> used improperly.

 ML>     For a full explanation of why there is no real GOTO (REXX is a
 ML> "dynamically scoped" language) see Mike Cowlishaw's
"The REXX Language:
 ML> A Practical Approach to Programming", 2nd edition [ISBN 0-13-780651-5].
 ML> This book (by the founding father of REXX) is the definitive description
 ML> of the "standard" version of the language, including the
reasons why
 ML> things are the way they are.  OS/2 REXX is a superset of standard REXX,
 ML> but the philosophy hasn't changed.
