What is the correct syntax for performing the following functions?

a.)  I have a variable ($MyVariable) with a string as its value. The string would be something like this:  "sometext||some-other-text".  I want to return just the text to the LEFT of the "||" (or any delimiter).

b.)Taking that one step further, if $MyVariable = "sometext||some-other-text::even-more-text".  I need functions to extract each portion of the string.

a.) Hmmm, Pier Xanthony?

b.)

($a, $b, $c) = split(/|/, $MyVariable);
This is assuming you meant there were three variable fields, else:
($a, $b) = split(/||/, $MyVariable);

Good answer--that worked great, except that you need to escape the |'s with "\".  Thanks!
