It only seems that way that if you don't use the WEXITSTATUS() macro, 
which right-shifts the exit-status by 8 and masks off the lower 8 bits 
of the shifted result, making the exit-status an 8-bit integer (-128 - 
127 or 0-255, depending on signedness).

Considering you're not a programmer (you said so yourself), it's strange 
that you've managed to get the unmasked, unshifted exit-status. You 
should either learn to program or not fiddle with popen() calls and the 
likes.
