How to read a switch

Archiver

I am using the BS2 and want to use 2 I/O pins for
connection to a switch. This switch will be used as a
table selection. The following is the truth table;

SW1 SW2 Table Selected
0 0 0
0 1 1
1 0 2
1 1 3

What I want to do is read the logic state of these two
inputs and have the software use the proper lookup
table.

Thanks for any help

John

switches var nib

switches = in1 << 1 | in2

branch switches, [noparse][[/noparse]action0, action1, action2, action3]
