maxLength

maxLength(): Integer;

The maxLength method of the String primitive type returns the declared maximum length of a string variable. If the string variable maximum length has not been declared, the value of the Max_UnboundedLength global constant in the SystemLimits category is returned.

The following example shows the use of the maxLength method.

vars
    stringValue : String[100];
begin
    stringValue := 'hello world';
    write stringValue.maxLength;   // Outputs 100
end;
