MAXCOL()
Determine the maximum visible screen column
------------------------------------------------------------------------------
Syntax
MAXCOL() --> nColumn
Returns
MAXCOL() returns the column number of the rightmost visible column for
display purposes.
Description
MAXCOL() is a screen function that determines the maximum visible column
of the screen. Row and column numbers start at zero in CA-Clipper.
If you use a C or other extended function to set the video mode, use the
SETMODE() function so your CA-Clipper application returns the correct
value for MAXCOL().
Examples

in which to draw a box, and then executes DBEDIT() within the box
region:
CLS

DBEDIT(1, 1, MAXROW() + 1, MAXCOL() - 1)
