Re: OPEN in RPGIII

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
