No, I spoke it wrong. Use <, >, et al for numbers and use EQ, et al for
strings. Sometimes the perl system will auto-convert, but only if the
string truly is a number. For example:
Strings (not NUMBERS!)
______________________
"Alpha 12345 Beta"
Strings that act like NUMBERS!
______________________________
"12345 Alpha Beta" (but is this behavior what you want or expect?)
True number conversions:
________________________
"0"
"1"
and the like. Did I explain good? -Sneex- :]
