IIRC, you must use 16-byte char fields in the RTNVAL() parameter in the
CALLPRC command:

dcl var(&enddate) type(*char) len(10) value('2002-12-07')
dcl var(&weekofyear) type(*char) len(16)
dcl var(&woytemp) type(*char) len(4)
dcl var(&woynbr) type(*dec) len(6 0)
callprc prc(rtvweekofyear) parm(&endddate) rtnval(&weekofyear)
chgvar var(&woytemp) value(%sst(&weekofyear 1 4))
chgvar var(&woynbr) value(%bin(&woytemp))

This is a documented condition of the CALLPRC command that its return values
must be defined in intervals of 16. I think it has to do with passing the
variable by reference.

Some of the above program is probably wrong, I'm offline at the moment.
