a directory AND a way to ignore the QB.LIB which seems to conflict
somehow with modem routines?
Because SHELL "DIR" requires much more memory (you need to load
COMMAND.COM in memory). Because it creates a file (which is not necessarly
desirable), because it's much slower (to load COMMAND.COM, to create a file
and to do a DIR) and because you don't have access to all the files you
want.
With FindFirst and FindNext, you only need the INTERRUPT[X] sub-
routine to be linked with your object file. DOS' DIR use these two function
also... But using them in your program directly let you access special
files (if you want to) like VOLUME label, system and hidden files and sub-
directory. Modifying the FindFirst subroutine a little lets you ignore
these files or include them if you want (for example, you can chose to dir
only the normal files (without getting the subdirectories)). DIR doesn't
offer you that flexibility.
I know, writing SHELL "DIR >" is much easier to do, but it's not
very professionnal.
By the way, QB.LIB should not comflict with your modem subroutines.
Unless you want to use QB.QLB (which is not the same...). If you want to
use QB.QLB and another quicklibrary, then you can't... you have to make
only one library like this:
LINK /Q MODEM.LIB+QB.LIB,,NUL,BQLB45;
This will link QB.LIB and MODEM.LIB to create MODEM.QLB which will
contain all the subroutines you need to do your modem things and
directories.
