Hello group,
I sent my code for the dat tape checking to a friend of mine who is been
my mentor on the HP3000. He made the following observations about my use
of the pause intrinsic in the father program. After reading several
emails in this list about the pause intrinsic and its need for a real
number motivated me to forward his email to the list.
thanks again to all who helped me on this project.

Joseph,
Looks like you wrote a winner...! Have you checked out the intrinsic
HPEXTIN? It converts an "alpha" number to a real number. It looks like:
Text-name WSREAL
001000 01 ONE-MINUTE PIC X(4) VALUE "0060".
001100 01 ANYVAR-LEN PIC S9(4) COMP VALUE +4.
001200 01 ANYVAR-DEC PIC S9(4) COMP VALUE +0.
001300 01 ANYVAR-TYPE PIC S9(4) COMP VALUE +1.
001400 01 ANYVAR-SCALE PIC S9(4) COMP VALUE +0.
001500 01 ANYVAR-DEL PIC S9(4) COMP VALUE +0.
001600 01 ONE-MINUTE-REAL PIC S9(9) COMP VALUE +0.
001700 01 ANYVAR-ERR PIC S9(4) COMP VALUE +0.
Text-name CONVREAL
001000 CALL INTRINSIC "HPEXTIN" USING ONE-MINUTE
001100 ANYVAR-LEN
001200 ANYVAR-DEC
001300 ANYVAR-TYPE
001400 ANYVAR-SCALE
001500 ANYVAR-DEL
001600 ONE-MINUTE-REAL
001700 ANYVAR-ERR.
001800*
001900 IF ANYVAR-ERR NOT = +0
002000 MOVE ANYVAR-ERR TO DIS-Z
002100 DISPLAY DIS-Z " INTRINSIC EXTIN' ERROR VALUE"
002200 STOP RUN.
I put them in a copylib and have access anytime. I forget what
manual I found this is but its not in the Intrinsic manual for
some reason, maybe the COBOL manual. I could probably find them
in the HPLaserRom if I looked. Anyway, you sound like you haven't
changed at all. Its good to see you still have that "fire in the belly"..!
