Function Start
Dim str, str2
str = "Is this string alphanumeric?"
if target.strlib.IsAlphaNumeric( str ) = true then

else trg.Message( "No" )
end if
End Function
In this example IsAlphaNumeric takes the input string and scans it checking to see if every character is alphanumeric. In this case IsAlphaNumeric would return false because there are spaces and a question mark.
