You did not state what version of OS/400 or i5/OS this is for? :-/

Also, you did not say whether you are coding in C or C++ ... :-o

AFAIK, "digitsof" is a C++ member function, and so it is not available in ILE C.

In ILE C/400, you could use the __digitsof operator.

Go to the InfoCenter for your version of OS/400 or i5/OS, and search for "digitsof".

Anyone understand why I can't use the digitsof keyword in a
declaration? It's based on a decimal field in a struct that is known
at compile time so I don't see the problem.

char periodstring[digitsof(myrec.DECFIELD) + 1];

I get this: "Integral constant expression with a value greater than
zero is required"
