Re: New Opcodes - %SETCELL

John,

Please forgive this post, I know it has nothing to do with the main
thrust of your message.

However, these numbers aren't that cryptic to me.... Although I'm
a little curious as to why you're using integers here instead of
named constants (do you plan to change them?)

The parameter that you're sending to open() (the "oflag" parm) is
looked at as a string of bits, each bit specifying a capability.
Theres a O_CODEPAGE bit, a O_TEXTDATA bit, O_CREAT bit, etc.

If you look at a binary representation of this parameter, as its
stored in memory, you'll see that each time you add another one of
the O_xxx flags, you're turning on a bit.

i.e.,               100000000000000000000000 (8388608 in binary)
                 + 1000000000000000000000000 (16777216 in binary)
                  --------------------------
                   1100000000000000000000000 (both flags turned on)


Makes perfect sense to me...
