compatible, looking at the code, I can see that the 'counter:=1' is just an
early termination clause.  If the variable 'counter' isn't needed after
that section, you could replace that line with 'break' which would exit the
loop immediately (which is what the code does now).

One shouldn't assume anything about the loop variable after the execution
of the loop anyway *except* the loop was left using Break or Goto.
