Thanks Scott,

I misunderstood 'varying'. I thought it meant that the it would accept
inputs of various sizes, not inputs only defined as varying size.

Hi Tim,

"Subr" is defined as 14A, fixed-length.   Low2Up() only accepts VARYING
fields as parameters.

If you define the parameter to Low2Up as a CONST or VALUE parameter, the
compiler will automatically convert the value for you.  That's a good way to
do this, since you're not returning the results via the parameter anyway,
you're returning them via the return value.

Passing the input parameter by CONST will make this routine more versatile
when you want to call it from other programs where they might or might not
use VARYING.

Here's how I'd code the Low2Up() procedure.  (Remember to change the
prototype to match!)

     P Low2Up          B                   Export
     D Low2Up          Pi          1000A   Varying
     D  String                             Like(Low2Up) const
     D                                     Options(*Varsize)
     D  Upper          C                   'ABCDEFGHIJKLMNOPQRSTUVWXYZ'
     D  Lower          C                   'abcdefghijklmnopqrstuvwxyz'

     D RetVal          s                   like(Low2Up)
      /free

        RetVal = %XLate(Lower:Upper:String);
        Return RetVal;

      /End-Free
     P Low2Up          E
