when:
n=1, POT returns the position of paddle #1
n=2, POT returns the position of paddle #2
n=3, POT returns the position of paddle #3
n=4, POT returns the position of paddle #4
The values for POT range from 0 to 255. Any value of 256 or
more means that the fire button is also depressed.
EXAMPLE:
10 PRINT POT(1)
20 IF POT(1) >=256 THEN PRINT “FIRE”
This example displays the value of the game paddle 1.
Note: a value of 255 is returned if no paddles are connected.
RCLR
Return color of color source
RCLR(N)
This function returns the color (1 to 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.
EXAMPLE:
10 FOR I = 0 TO 6
20 PRINT “SOURCE”;l;”IS COLOR CODE”;RCLR(l)
30 NEXT
This example prints the color codes for all seven color sources.
