Strange results in FB with PRINT USING.

well, QB would require that you start the IDE like this:
qb /l dsockqb.qlb

DSock is only for QB.  You may use Winsock directly with FreeBASIC, however (and since you would need a Windows computer to run DSock anyway, you might as well use FreeBASIC with Winsock)

In FreeBASIC, header files can directly refer to static libraries so the /l bit is not needed.
