HI
One local resident perl expert (speaking at a LUG) suggested modifying use
of the strict pragma with vars, as in :
#!/usr/bin/perl -w
use strict vars;
I find however that it's necessary to put 'vars' in quotes to avoid a
warning message, viz.:
Unquoted string "vars" may clash with future reserved word at
/usr/local/bin/srns line 2.
When I mentioned the need for quotes, neither the teacher nor any perl
user in the LUG meeting was aware of such restriction.
Why such a difference from one user to another in Perl? We are all using
perl 5.8 (perhaps some are on 5.6).
$ perldoc strict # OR ...
$ man 3 strict # ...brings up description /examples with double
quotes around "vars" (and .....# "sub" ,
"refs"). ...One textbook example i have shows single quotes.
BTW it appears that Perl 5.8 running on Cygwin /W2K doesn't generate the
error message.
Other, 'normal' linux platforms give the warning (for this perl newbie at
least).
TIA
