RCLR
ROOT
—Return color of color source
RCLR(N)
This function returns the color (1 through 16) assigned to the color
source N (0< = N < 6), where the following N values apply:
0 = 40-column background
1 = bit map foreground
2 = multicolor 1
3 = multicolor 2
4 = 40-column border
5 = 40- or 80-column character color
6 = 80-column background color
The counterpart to the RCLR function is the COLOR command. See
RSPRITE and RSPCOLOR for current sprite colors.
EXAMPLE:
10 FOR I = 0 TO 6
20 PRINT "SOURCE";I;"IS COLOR";RCLR(I)
30 NEXT
This example prints the colors for all seven color sources.
—Return current position or color source of pixel cursor
RDOT(N)
where:
N = 0 returns the X coordinate of the pixel cursor
N = 1 returns the Y coordinate of the pixel cursor
N = 2 returns the color source of the pixel cursor
This function returns the location of the current position of the pixel
cursor (PC) or the current color source of the pixel cursor. Note that
RDOTdoes not return scaled coordinates.
EXAMPLES:
PRINT RDOT(0)
PRINT RDOT(1)
PRINT RDOT(2)
Returns X position of PC
Returns Y position of PC
Returns color source of PC
