Length 


 

Length ( string ) -> Function result 
Parameter Type   Description
string  String in String for which to return length
Function result  Longint in Length of string

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

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
