Re: programming language genealogy

Steve,

>and "*entry plist" ?

Yes, unless you count using EXIT to call an assembler routine.  But those
weren't external program calls anyway.  The SUBRxx routines were link edited
into the program object.

Ultimately, RPG II got the CALL opcode as well, but not until long after RPG
III.
