I did some testing. You're probably missing the DTAARA keyword in
column 40 of the UDS statement. Using the MAIN keyword means that the LDA
(and other data areas) cannot be automatically handled by the RPG program.
Therefore, you must explicitly tell RPG that your UDS is a data area by
specifying the DTAARA keyword on your UDS statement and coding the IN,
OUT, and UNLOCK op codes in your calculations.

When you use the MAIN keyword, the UDS is still automatically handled by the RPG program. But the automatic handling only applies to locking the data area during module initialization.

The presence of the DTAARA keyword causes the IN, OUT, and UNLOCK opcodes to be allowed with the data area. That rule also applies to cycle programs (no MAIN or NOMAIN keyword).
