Actually, I've never found the need for a %value BIF, since all I have
to do is create a DS of type A and type S.  I move the number string
to the string variable, and pull the value out of the number variable.

Although I agree a %value BIF would make things simpler, it is not
absolutely necessary.

D                        DS
D NumberString                   15 A
D NumberValue                   15 S

C*** NumberString contains '12345'
C                  EVAL NumberString = SomeString
C                  EVAL SomeNumber = NumberVal
C*** Now SomeNumber contains the value 12345
