Inputs/Outputs
Hi,
I am just wondering how you can control which are inputs/oupts with the BASIC
command "INPUT" or "OUTPUT"
But I don't want to write:
Input 1
input 2
Input 3 Etc
Can it be done like "Inputs 1-3" or "Input 1 TO 3" or something simmilar?
Thanks
Ben

Dirs=%0000000010110010 ' Define which of P15-P0 are in-0 or out-1
NOTE: The leftmost digit is for pin15, rightmost is for pin0
The above 2 lines define P15-P8 as inputs, P7 is an output and starts
high,P6=input,P5-P4 are outputs starting with logic low, P3-P2 are inputs,
P1 is an output starting logic low, and P0 is an input.

Where 0 is an input and 1 is an output.
You can also use DIRH (P8-15), DIRL (P0-7), DIRA, DIRB, DIRC, and DIRD
(four bits each starting at 0 and counting up).

them:
The predefined name DIRS represents the direction state of the 16 bit
word for the I/O pins (0-15) in a BS2, DIRL identifies the first bytes
(8 bits, 0-7) and DIRA identifies the first nibble (0-3).
So to make pins 0-3 input just do INPUT DIRA. To set all 16 pins as
input do INPUT DIRS.
If you preferred your own meaningful labels do:
MYBITS VAR DIRA ' creates alias to pins defined by DIRA
INPUT MYBITS ' sets first nibble, pins 0-3, as input
I think this does what you want.
