Length
Length ( string ) -> Function result
| Parameter | Type | Description | |
|---|---|---|---|
| string | String | 🡒 | String for which to return length |
| Function result | Longint | 🡐 | Length of string |
Description
Length is used to find the length of aString. Length returns the number of characters that are in aString.
Note: In Unicode mode, 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
This example illustrates the use of Length. The results, described in the comments, are assigned to the variable vlResult.
vlResult:=Length("Topaz") // vlResult gets 5
vlResult:=Length("Citizen") // vlResult gets 7
