CATCH inside a FOR loop and out? [message #88322]

Say I want to catch two kinds of erros:

1. if error happens inside a for loop I want to deal with it and then continue with i++
2. if error happens outside the loop I want to return -1

Can this be done?

Thanks,
Gianguido

Here is what I got, which catches erros inside the loop and behaves like I want it to, but I would like to deal with ;NEWERROR differently...

compile_opt idl2

a = 10*(indgen(10)+1)
FOR i = 0, 9 DO BEGIN
CATCH, Error_status
IF Error_status NE 0 THEN BEGIN
CATCH, /CANCEL
PRINT, 'GCError index: ', Error_status
PRINT, 'GCError message: ', !ERROR_STATE.MSG
i++
if i gt 9 then return
ENDIF

IF i EQ 3 THEN print, i, a[100]
IF i EQ 7 THEN print, i, a[100]
IF i NE 3 AND i NE 7 THEN print, i, a[i]
ENDFOR

;NEWERROR

RETURN
END
