All BASIC commands
Section 4-2

4-2-175 OPEN_WIN
/i
Example
OP(12,1)
OP(12,ON)
These two lines are equivalent.
Example
OP(18*256)
This line sets the bit pattern 10010 on the first 5 physical outputs, out-
puts 13 to 17 would be cleared. The bit pattern is shifted 8 bits by multi-
plying by 256 to set the first available outputs as outputs 0 to 7 do not
exist.
Example
VR(0) = OP
VR(0) = VR(0) OR $FF00
OP(VR(0))
This routine sets outputs 8 to 15
ON
and all others off.
The above programming can also be written as follows:
OP(OP OR $FF00)
Example
val = 8 ' The value to set
mask = OP AND NOT(15*256) ' Get current status and mask
OP(mask OR val*256) ' Set val to OP(8) to OP(11)
This routine sets value
val
to outputs 8 to 11 without affecting the other
outputs by using masking.
