See perlfaq7 on lexical vs global variables and strict. Basically, if you `use strict` (and you should) variables declared with "my" can only be used from the declaration on until the end of the scope they're declared in: `sub mysub { my $var1 = 1; # here you can use $var1 } $var1 = "boo"; # compile error: there is no $var1 declared in this sco +pe.` [download] Using "my" (lexical) variables together with "strict" will significantly reduce the risk of typos or modifying "unrelated" variables.
