if used four times, does a sub run four times?

[bazz]

Maybe I'm overthinking here but....

I want to use the data gathered by a sub, on four occasions. Does this mean that the sub will run four times or can perl cache the data from the first sub-run and use it throughout the script?

If you put the data into global vars, you can use it anywhere, anytime, as many times as you want within the execution of the script.

Thanks FishMonger. :thumbsup:

Though if the program gets large enough, accumulating lots of global variables can start to make the code a bit sloppy. If you need to have data persist across subroutine calls then you might want to consider taking an object oriented approach.

Thanks Jeff, I'll google that and see what it entails.
