To me, it is much clearer to be explicit, including the concatenation, e.g.
"DELETE " || foo
That overkill is apt to confuse a POSIX shell partisan who would
see the blank as part of the command name
Isn't Rexx assembling it all into one string, which gets then run as the
command?
There can be significant spaces between parts of the command, and no
spaces allowed in other parts. So you could have e.g.
"DELETE ABC" || suffix
or
"DELETE" prefix || suffix
which is very different from
"DELETE" prefix suffix
and it can get much more complex. I would rather use a consistent
concatenation operator and explicitly insert spaces rather than rely on
getting the right concatenation operator in the right place.
It's a matter of style, but there are some things that just look like
potential bugs to me.
