Sure.  Try compiling this program on V4R5, or on V5R1 with TGTRLS(*PRV):

D proc            pr
D   arrayParm                    1a   dim(max)
D max             c                   10
C                   return

But that's not the case that causes the problems.  Try this case.  The
DIM on the second last line gets this message about DIM having to
be pre-defined.  But there it is, defined right there on line 1.  The
problem is that when the compiler is scanning a subprocedure,
global references are not resolved until it reaches the end of the
subprocedure, because of RPG's allowance of forward-referencing.

D max             c                   10
D proc            pr
D   arrayParm                    1a   dim(max)

C                   return

P proc            b
D proc            pi
D   arrayParm                    1a   dim(max)
P proc            e
