goto-do-label

Hello,

I find, when using Mathematica, the followng programming 
problem: The instruction 'Goto' cannot be used to jump
out of a loop 'Do'.

For example, the following programme here shown
in a summarized form:

     variable[arguments_]:=Module[{ ... },
     .....................................
     Do[
     .....................................
     Goto[end];
     .....................................
     ,{i,1,5}];
     .....................................
     Label[end];
     .....................................
     ] (* end of Module *)

alwais gives me the following error message:

     CompoundExpression::::goto: Label[end] requested by Goto not found.

I naturally find ways to get round it, but I would
like it to function as expected (for example,
as in FORTRAN).

Is this correct ?  Is there any way to correct it ?
