bounds check in array subscripts

[Mark Fardal <fardal(at)weka.astro.umass.edu>]

Hi,

just noticed something odd, running IDL 5.1 on a Debian Linux Pentium box.

IDL> x = findgen(3)
IDL> subs = indgen(10)
IDL> print, x(subs)
      0.00000      1.00000      2.00000      2.00000      2.00000      2.00000
      2.00000      2.00000      2.00000      2.00000
IDL> print, x(9)
% Attempt to subscript X with <INT      (       9)> is out of range.
% Execution halted at:  $MAIN$              1 sfr.pro

is this the expected behavior?  I am suddenly filled with fear that
all of my programs have undetected array subscript bugs.


thanks,
