The UNIX System services comes closer. The command:
myrexx 'a quoted string' 'another quoted string' simpletoken1
simpletoken2 ...
not only concatenates the tokens into ARG(1) but also assigns them to
__ARGV.1, __ARGV.2, __ARGV.3, __ARGV.4, ...
Regina has a command line option to select Rexx-like parsing (default)
or shell-like parsing.
in fact, IKJPARS weakens EXECIO. In CMS Rexx, I can simply say:
EXECIO 1 DISKW file-spec (string It's a string!
... (any expression). IKJPARS would prohibit this. I suspect this was
a deciding factor in not providing TSO Rexx EXECIO a STRING option
and requiring instead the cumbersome:
X.1 = 'It''s a string!'
'EXECIO 1 DISKW file-spec (stem X.'
