[SCRIPT] Variable Prefix

[Adrianis]

Not sure exactly what the 'a' is (possibly meant to just be a, as in 'a string', although Amns suggestion sounds pretty reasonable), but 'l' is probably for long, which is an integer type in a number of languages
as - string
al - long
ab - bool
af - float

I usually just use my own, str in bl & fl to append the parameters
