How does the | connect flags? In TOTWGPG, LaMothe refers to them as "logically ORing" the flags together? Isn''t or || not | ? I''ve never seen | in use with C++. Can anyone explain this to me? tcache Contact Me ----------- AH! MY BRAIN IS GOING TO SELF-DETONATE! -- Yours Truly (Jan, 2003)

The | is a bit-wise OR operator whereas || is a logical OR operator

Ok say you have two flags. FlagA and FlagB

In binary they look like:

FlagA: 10000000
FlagB: 00000001

FlagA | FlagB == 10000001
