Remove the CVTOPT(*VARCHAR).

This data structure is wrong, and makes no sense at all. Positions 3 & 4 in your definition are both part of the character data AND part of the length! A VARYING field only uses 2 bytes for the length, so it makes no sense to declare positions 1-4 as the length -- that's 4 bytes.
Similarly, the B data type is wrong. Though, it might not matter with a 255 character long field. There's absolutely no advantage to declaring this field as "B". Use the U data type, it's faster, and more correct for this application.
Futhermore, you could have garbage in the "data" field, since the system won't necessarily fill the unused portion with blanks.
I'm not sure why you're using a data structure at all. Why not simply do the following:
C EVAL WkEmp = InEmpLet the system convert it from VARYING to fixed-length. Why reinvent the wheel when it's built into RPG?
