I use script(1) if my terminal emulator doesn't maintain a log.

(I've used this to embed Rexx in a shell script.)
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)?
