Hi folks I've got a query about variable initialisation. I want to initialise a list of variables to an empty string, but I'm having troubles.
What's the best wat to do this? If I use the following I get: [EMAIL PROTECTED] gary]$ cat t #!/usr/bin/perl -w use strict; my $fred=$ginger=''; print "fred=$fred\n"; print "ginger=$ginger\n"; [EMAIL PROTECTED] gary]$ ./t Global symbol "$ginger" requires explicit package name at ./t line 5. Global symbol "$ginger" requires explicit package name at ./t line 8. Execution of ./t aborted due to compilation errors. [EMAIL PROTECTED] gary]$ but if I use: [EMAIL PROTECTED] gary]$ cat t #!/usr/bin/perl -w use strict; my ($fred,$ginger)=''; print "fred=$fred\n"; print "ginger=$ginger\n"; [EMAIL PROTECTED] gary]$ ./t fred= Use of uninitialized value in concatenation (.) or string at ./t line 8. ginger= [EMAIL PROTECTED] gary]$ -- Gary Stainburn This email does not contain private or confidential material as it may be snooped on by interested government parties for unknown and undisclosed purposes - Regulation of Investigatory Powers Act, 2000 -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
