In ANSI and SAA REXX, string is the only type and all numbers are strings,
although some implementations treat numbers as a special case for optimization.
DATATYPE9n) operatesw on an expression and classifies its value. In oorexx,
things are different with classes and method, as in
say 'x.'~class
The String class
................................................ REXXTRY.CMD on OS/2
say x.~class
The Stem class

Subject: Re: Rexx routine to dump all variables when debugging?
In Classic Rexx the main types are string and number. All Rexx has datatype().
It tells you if a string is Alphanumeric, Binary, Lower case, uppoer case,
mixed case, a number, a symbol (a vakid Rexx symbol, a whole number, or a hex
number.
NetRexx has the JVM’s introspection (reflection).
Open Object Rexx also has a complete set of reflection operations. In ooRexx
you can send a message to any object to get to know its Class. A complete
reference card for ooRexx has been made using reflection.
best regards,
René.
