[comp.lang.pascal] ?control runtime error in TP

cncst@unix.cis.pitt.edu (Christophe N. Christoff) (06/30/90)

TP provides very good control on I/O, how one can control
over runtime error/stack error?

Also, how one can tell the screen mode without destroying it? I
mean one load the program in whenever the current mode is text
or graphics mode, and the program can print information about
the screen mode.
