If I understand the problem, you want to use ONE input port, which to the stamp is either a 1 or a 0, and connect two buttons to it to detect either a 1 or a 0 .... it doesn't seem possible.<br />
<br />
You'd need a tri-state input for that...which would be &quot;seen&quot; as a 1 a 0 or &quot;not a 1 or 0&quot; as the third state. I don't believe the stamp can do that.<br />

Now it you're using two input ports, no problem!

You'd need a tri-state input for that...which would be "seen" as a 1 a 0 or "not a 1 or 0" as the third state. I don't believe the stamp can do that.

OK LRHGuy, lets use two input ports. How would you write the code &nbsp;(just an example)?

Lets say I have two push button switches connected to the input port of a basic stamp. What I want to know is how to write a simple program to input a &quot;1&quot; when the 1st button is press and a &quot;0&quot; when the sexond button is pressed. I'll have the the 5v connected to both switches and a not gate connected to the second.

BASIC STAMP : How to input bits into an accumilator

An assembly language (or assembler language) is a low-level programming language for a computer or other programmable device in which there is a very strong (generally one-to-one) correspondence between the language and the architecture's machine code instructions. Each assembly language is specific to a particular computer architecture, in contrast to most high-level programming languages, which are generally portable across multiple architectures, but require interpreting or compiling. Assembly language is converted into executable machine code by a utility program referred to as an assembler; the conversion process is referred to as assembly, or assembling the code.
