Hi Leslie,
I never worked with Rexx on a main frame, so hostemu is completely foreign
to me. So, I can't help much there.
I vaguely remember that there are some special rules about quoting.
Combing the error code 20, Symbol Expected, and this:
'diskw "/home/leslie/html/private/'directory.d'/index.html" (finis stem
html.'
I would guess the quoting is not correct. Error code 20 has this subcode:
906
Symbol expected after "(" of a variable reference. Or maybe it has to do
with directory.d.
I notice that no matter what the error# is, sysGetErrNoMsg() seems to
return "Unknown".
Seems like a bug to me. I haven't looked at the Unix Extensions package at
all, so again I can't be help much there.
David Ashley did both of those extensions and would be the best person to
explain what is going wrong for you. He is out of touch right now, so he
won't respond immediately. He'll be back in touch in August.
If I were you, I'd investigate the quoting in your use of hostemu. I'll
try to take a look at the Unix Extensions package if I have some time. You
should bring this up again on the list in August to try and get David's
attention.
Personally, I'd open bugs about things that don't seem to work. And open
up documentation bugs where there seems to be lack of information to use
these packages.
