length

length ( aString : string ) : integer

Parameter	Type		Description
aString	string	→	String for which to return length
Result	integer	←	Length of string

Description

length is used to find the length of a aString. length returns the number of characters that are in a aString..

note

When you want to check whether a string contains any characters, including ignorable characters, you must use the test if(length(vtAnyText) == 0) rather than if(vtAnyText == ""). If the string contains for example char(1), which is an ignorable character, length(vtAnyText) does return 1 but vtAnyText == "" returns true.

Example

 var vtResult : string
 vlResult = length("Topaz") // vlResult gets 5
 vlResult = length("Citizen") // vlResult gets 7
