I write
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i program
testerror; {$MODE OBJFPC}{$H+} uses  sysutils;  var  s1,s2: String; 
n: integer;begin  s1:= 'TEST3';  s2:= 'TEST1/TEST2/TEST3';  n:=
s2.LastIndexOf(s1);  WriteLn('n = ', n);end. 
I compile
Code: [Select]fpc -B -glh testerror.pas

No, this method is not implemented in FPC 3.0.4

No it is already in 3.0.4. (Otherwise it would not compile). It may be
that there was a bug which should be fixed in FPC 3.2.0.
Anyway your code compiles and works with 3.2.0 and trunk 3.3.1-41807.
I tested on Raspbian Jessie.

Many thank for try 3.2.0. I now usage more better solution and not use
LastIndexOf 

I also try 3.2.0 and write that work. I solve thread. Fix is 3.2.0 not
use LastIndexOf fpc 3.0.4
