the value of MORE-FLAGS was x'04' not x'40'. Gene, the code you are
looking at actually came from my old SCRNIO program which was carried
over from S/38. You may remember that I used that program when I gave
MI-classes back in 1990 in Amarillo. SCRNIO has been used in production
by hundreds of installations since 1989, but was recomplied at PentaSafe
in 1999. Maybe the meanings on the MORE-FLAGS have changed slightly
over time. If you list the MI-code produced by RPG today, you'll see this
declaration of MORE-FLAGS (including the comments):

DCL DD .UFCBFLG2 CHAR(1) DIR /* FLAGS */
/*BIT 0 COUNT INVOC MARKS */
/*BIT 1 TAPE CLOSE PARMS */
/*BIT 2 MULTIRCD SPECIFIED */
/*BIT 3-7  UNSED */     (sic)

somewhat different from what you have.
I don't know what the correct settings should be.
In my newest version of SCRNIO more-flags is
set to x'00'.
