Yeah, but it separated the men from the boys, Norm. .-)

Correct.
Ah, those were the days, Level Break indicators, Matching Record indicators,
Direct Files.
Absolutely bloody awful stuff.

Mark,

There were no structured op-codes (IF, DO) on the S/34 - except through
Schuette's (sic) RPG II 1/2.

They were added to the /36 when the Advanced/36 models came out (SSP 7?),
but they were somewhat crippled.  CAB was never part of IBM's RPG II
compilers.

Hi, Terry:

IBM System/3 RPG II had only COMP, indicators, GOTO and TAG, and EXSR, 
BEGSR and ENDSR (for "control flow").

With the IBM System/34, IBM added "structured programming" opcodes 
(still calling it RPG II):

    IF - ELSE - END
    DOWxx   - END, DOUxx - END, DO - END
    CASxx

CALL and PARM were added with Systen/36 Release 6 (VASP).

I think CABxx was introduced with System/38 RPG III.

(Anyone else remember those details any better?)

HTH,

Mark S. Waterbury
