When writing sample code one often finds themselves thinking "what should I name this meaningless variable?" Since often the variable names are incidental to the point of the sample code it's become a convention to reuse the names foo and bar to save time and effort. These names are permutations from the earlier references to fubar and are meant to be humorous. They have no other intrinsic value or significance. They are not special global variables like $_ or $& or $# or $/ or any thing else found in the perlvar documentation. They are just funny names. Laugh. Or at least grin. maybe.

What is the meaning of foo in perl programming ? I see quite a lot of sample codes use foo..... besides, and what is bar ? Is that a certain type of variable ?? just like a number or something like escape char ??
