Before()
FUNCTION: before(<string1>, <string2>)
This function is case sensitive.
Returns the portion of <string1> that occurs before <string2>. If <string2> does not occur in <string1>, the entire string is returned. If you want to return the portion of the string after the first space, use the first() function instead.
Examples:
> say before(This is a test,a)
You say, "This is "
> say before(This is a test,is)
You say, "Th"
> say before(This is a test, nope)
You say, "This is a test"
