I think what Bean is trying to say that LOOP NEVER is a convenient way to create a custom label for when your complex expression is false.  Without it you could do something like this:

[code]Evaluation:
  IF a <> 1 THEN
    IF b <> 2 THEN
      GOTO Evaluation_Failed
    ENDIF
  ENDIF

Evaluation_Succeeded:
  ' handle it
  GOTO Next_Process

Evaluation_Failed:
  ' handle it

Next_Process:
  ' handle it[/code]

One of the things that the SX/B reveals is that many of our *fancy* programming structures, things like IF-THEN-ELSE, are executed with simple test-and-jump code with the compiler automating the labels that I created manually in the example above.
