Ah you 'I get to work on new code' developers have all the luck!  <grin>

As I alluded to in my trite remark above, /COPY may well be a warning flag
in new code.  Consider older RPG II code that has /COPYs for standard code
blocks like "get the current run date from the constant file."  That tends
to stay in place from RPG II to RPG III and now into RPG IV until we get
around to having to maintain it, and THEN we can move the /COPY from the C
specs to the D specs!  (from code block to prototype include.)

Don't I know it!
