(Use the -e command line switch, then you can run and test perl syntax entered in the command line.) You can enable strict and warnings on the command line. That ought to fix it fix it. `perl -cw -Mstrict -e "Welcome Back"` [download] yields: -e syntax OK Oops. It works with a single word: `perl -cw -Mstrict -e Welcome` [download] Bareword "Welcome" not allowed while "strict subs" in use at -e line 1. -e had compilation errors. But with two words, it's problematic: `perl -MO=Deparse -e "Welcome Back"` [download] produces: 'Back'->Welcome; -e syntax OK Syntaxwise, it's OK, even under strict. This is the so-called indirect object syntax, which often is problematic as it doesn't always work as intended. I wish strict had a way to disallow it.	[reply] [d/l] [select]

Barewords which do not otherwise cause a syntax error only give rise to an error when `strict 'subs'` is in operation, thus you will need to do something like: `perl -Mstrict=subs -c file.pl` [download] I have limited this just to the 'subs' stricture because I don't know anything else about the code that you are accepting. Of course this might not be what you are asking at all. /J\	[reply] [d/l] [select]

`$ perl -c "Welcome Back" Can't open perl script "Welcome Back": No such file or directory` [download] I'm not at all sure what it is that you're asking. Can you be a little more explicit please. -- <http://dave.org.uk> "The first rule of Perl club is you do not talk about Perl club." -- Chip Salzenberg	[reply] [d/l]
