Hi guys,

according to the manual, array subscripts are converted to long (or long64
on 64 bit systems) before use if necessary, so an explicit conversion
should not affect the result.

IDL> print, !version
{ x86 linux unix linux 6.3 Mar 23 2006 32 64}
IDL>
IDL> a=lindgen(10)
IDL> print, a[[long(-1ull)]]
0
IDL> print, a[[-1ull]]
9

Is it a bug or I am missing something?

regards,
lajos
