Subject: Array question...
OK here's the problem:
I have an array that may or may not have been assigned to, if it has been
assigned to I need to do one thing, otherwise I need to do something else.
I've tried many variations, but I'm having trouble determining if it has
been
assigned to.
if(undef @myArray) {
# Do thing1
} elsif(!undef @myArray) {
# Do thing2
}
and
if ($myArray[0] ne "") {
# thing1
} else {
# thing2
}
as well as a few other variations. Printing out the array BEFORE the if
block
shows nothing in the array, yet it does thing1.
After trying many different methods, I am totally lost, please help me!
TIA
