[alt.msdos.programmer] checking the kb shift status

djb@wjh12.harvard.edu (David J. Birnbaum) (06/03/90)

Programs that monitor the keyboard status (such as tsr that
use ctrl+shift as a hotkey) seem to read the keyboard status
in one of two ways.  Some check 0:0147, while others use
function 2 of int 16h (which apparently does the same thing
for you).  Is one method better?  Is one better for certain
types of applications?

Please respond by email.  I will post a summary.

Thanks,

David

Once again, apologies for my last posting under this title.  THis is
the second time that our news software has reposted a two-month old
posting under a new date; I received many informative replies when I
first posted this inquiry and certainly didn't deliberately repost it.

Until further notice, please to do not reply to any postings originating
from me.  I will work with my system manager to try to prevent further
spurious repostings to these groups.
