On z/VM and my RHEL 7 laptop, I have this tool that I use.
Perhaps you can extend it to fit your purpose.
On a command line, I type:
calc <rexx statement>
[<mydir>]$ cat ~/sbin/calc
#!/usr/bin/rexx
/* REXX */
trace errors
rc = 0
PARSE ARG expr
IF expr <> '' THEN DO
numeric digits 20
interpret 'Say' expr
EXIT
end
exit rc
===
I hope this helps!

Yes, there is REXXTRY. But it doesn't do what I am describing. It will do
some of it, sort of. It will accept a REXX statement from the input and
execute it. There is no way to put the statement(s) to execute on the
command line itself. And there is no implicit loop capability which
automatically reads the input file(s) and assigns the record content to a
variable, $_ in my example. Also, it will not accept multiple input
statements and create a REXX program from them all, then run it. It is, at
best, clumsy. At least in my opinion.
