Re: jvalue in QSYSINC/QRPGLESRC,JNI

Except that RPG doesn't allow object subfields, so the L member can't be
defined like(jobject).  An object reference is actually an integer, so
jint (or maybe better 10i 0) has to be used for that subfield.

The problem with that is that you can't assign an object to an integer or
vice-versa.

Right; the only way to set jvalue.l defined like(jint) given the
subfield restriction, is to have a spoof procedure that "converts" an
object reference to an integer.

 * Official prototype
D refToInt        pr            10i 0 extproc(refToInt_procptr)

D refToInt_procptr...                                                  
D                 s               *   procptr inz(%paddr('refToIntSub')

 * Internal prototype
D refToIntSub     pr            10i 0 extproc('refToIntSub')  
D    ref                        10i 0 value                   

 * Actual procedure, called through the refToInt prototype
P refToIntSub     b                   export  
D refToIntSub     pi            10i 0
