The term "pragma[t]" appears to have originated with ALGOL-68. But processing directives are much older. How long has assembler had a PRINT directive, very similar in purpose to //* FORMAT? On JES2-only or JES3-only constructs: IIRC, there was an interval during which the JCL OUTPUT statement was supported by JES2 but not by JES3. What happened at that time if a programmer attempted to run a JES2 job containing "OUTPUT" on JES3? o OUTPUT was quietly ignored? o OUTPUT was ignored except for a warning? o Syntax error? I consider the "quietly ignored" behavior the worst ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
