Like CLIST, EXEC and EXEC 2, it was intended as a scripting language and, IMHO, is well suited for that purpose, although there are some enhancements that would make it a better scripting language, >it allows (sometimes requires) a function's definition >before its use, WTF? REXX function are normally written after their use, for very good reason. The one exception is that when one function calls another it doesn't matter which comes first. >Why does the Rexx standard not provide a means for >PARSE EXTERNAL to report >end of input (e.g. SYSTSIN)?

Why doesn't z/OS have a REXX command? Why can't IRXJCL accept a script in SYSIN? (There's a bizarre cheat; unsupported.) Why doesn't OMVS Rexx have a REXXPATH environment variable to search for external functions (and another for function packages)? I do not consider Rexx a candidate for a shell, first because it allows (sometimes requires) a function's definition before its use, with the consequence that a typo in a function name causes the interpreter to devour input indefinitely. Why does the Rexx standard not provide a means for PARSE EXTERNAL to report end of input (e.g. SYSTSIN)? -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
