RE: CONST vs. VALUE

[Dan Miller <DanM@xxxxxxxxxxxxx>]

Good question.  I had to look it up.

CONST is used to indicate that a parameter passed by reference is read-only.

The VALUE keyword cannot be specified for a parameter if its prototype was
defined using the EXTPGM keyword.

What's the difference between using CONST and VALUE on ILE parm lists?  I
have always used VALUE.  It seems to do the same thing as CONST.

ie:
 D QCmdExc         PR                  ExtPgm('QCMDEXC')       
 D                              256    Options(*Varsize) Const 
 D                               15  5 Const     

Just wondering.

Brad
