Rob, you can use a prototyped call for a subprogram (the prototype gets 
the EXTPGM keyword).  Also, subprograms do support CONST for parameters 
(but they don't support VALUE).

It's true that you can't return a variable from a program, so you would 
have to code the return value as a parameter:

 MySubprogram(RealVariable: 3 * WorkVar);

or if RealVariable isn't the same type as the parameter

 MySubprogram(TempVar : 3 * WorkVar);
 RealVariable = TempVar;
