[Gambas-user] Reading hex from a string socket read

[adam krell]

Ah, yes, that seems a little better for my int values.
   Some of my data is ints and others are hex codes
and still others are strings. I was using a variety of
functions to decode the data.  I also had to implement
a manual "buffer counter".  As was mentioned,
pack/unpack type command or sprintf() would be a fast
way to do this kind of stuff.

 I was mainly concerned with increasing speed.  I
found out that some debug code I had was slowing it
down.  When I removed that the speed was fine.

Thanks,

Adam
