[ string->isalnum ]


[String->IsAlnum] checks whether a specified character within the string object is alphanumeric. If the parameter specifying the position of the character to be examined is omitted, then the default position 1 (or first character in the string object) is examined. The method returns True if the examined character is alphanumeric or False otherwise.

Use the [String->IsAlnum] method. The following example returns False since the sixth character of the string is not alphanumeric, but a space.
