Just wondering: is there a fool-proof way to detect if a command exists in
DCLTABLES?
The f$type() lexical works fine for symbols, and the dcl$path search will
find other commands, but as it stands, the WWWEXEC.COM file will not work if
Perl has been installed in DCLTABLES.
It would be nice if it could detect this - it's a pity to have to edit it.
One could try "perl -v" and check for %DCL-W-IVVERB, but that is a bit messy
(and expensive ?).
Is there a generic way of doing this?
Sorry, this is a bit off-topic (but it might come in handy for configuring
Perl, I guess!)
