I have no problems with using ENDs in most places. It is a matter of
properly placed '&'s and '$'s. I saved the following code, which does
nothing worthwhile, as TEST (without the .pro) and was able to use it in
$MAIN$, procedures, functions, other loops, and at the command prompt as
@TEST
and it also works just by copying the block to the command prompt.
This works on my Unix box, IDL5.1, but I would be surprised if this was
version or platform dependent. Granted, this makes the code look a tad
ugly, but I have had occasions where it was handy to "batchify" a couple
hundred lines of code like this.
;;;;;; TEST ;;;;;;;;;;;;;;;;;;;;
i=0
FOR j=0,2 do begin $
i=i+1 & $
IF (j ge 1) then begin $
i=i+1 & $
REPEAT begin $
i=i+1 & $
WHILE (i lt 20) do begin $
i=i+2 & $
CASE j of & $
0 : i=i+1 & $
else : i=i-1 & $
ENDCASE & $
ENDWHILE & $
ENDREP until (i gt 25) & $
ENDIF & $
ENDFOR
print,i
