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
