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

Hmm, this is a real memory test for me, but are you sure that RPG II had
the CABxx and CASxx opcodes? I only remember these from RPG III.

CVTRPGSRC, of course, does not claim to work for RPG II.

Cheers,
Terry.
