NUMCOL()

Syntax:     NUMCOL()

Returns:    A numeric value.
            The number indicates the number of column available on
            the screen.

Usage:      NUMCOL() can be used to set the width of the screen so as
            to determine the line break for an output.  In contrast to
            MAXCOL(), this function also returns the width of the actual
            screen when using windows.  It can be 40 columns for
            certain video cards (e.g.,CGA), depending on the setting of
            the cards.  However, there will as a rule be 80 columns.

Notes:      The BIOS setting is returned to the program.

Library:    CT1.LIB
