 This is a workaround.

If you create an externally defined ds referencing SAMPLE that is placed
BEFORE your use of the like () in your data structure - your field will
have the same attributes as the referenced field(zoned).


I can't remember IBM's explanation at all - except it was like 'that's the
way the compiler works'.  I do remember the explanation included a
discussion of events that occur on each of the multiple passes the RPGIV
compiler needs to resolve data references.

Does anyone else see this as a problem?
<<PF Source>>
      A          R SAMPLE
      A            ZONED          3S 0
      A            ZONED2         3S 0
      A            ALPHA          3A

<<RPG IV SOURCE>>
      Ftest      ip   e             disk
      Dstruct           ds
      Dzoned
      Dalpha
      Dzoned#2                              like(zoned2)
      Dalpha#2                              like(alpha)

zoned#2 is built by the compiler as a PACKED field. When I checked the
compile listing it even said zoned2's program format was packed while zoned
was zoned.
OS/400 = V3R2
Cum = most currently available.
IBM hasn't let the developers give us the ability to use like() AND
override anything but the length yet here it seems that the like() doesn't
even produce the same data type.
