Wouldn't the ALIGN keyword do the trick?

Pointers must be aligned on 16-byte boundaries in a data-structure, so since
the first subfield is 65 bytes, the RPG compiler adds 15 blank spaces after
that and then aligns the PROCPTR so it starts at position 81.

Either change the order of the fields or (probably easier), make the first
field 64 bytes - that will allow the PROCPTR to start at position 65,
leaving no blank spaces.
