need help with basic stamp code
I have a small alarm project that have to use basic stamp language to determine whether the input to the alarm is 5V or ground (0V) via pin 1. If the input is 5V then the result is logic 1 otherwise the result is logic 0 . How can I put them in basic stamp language?
there is a sample code input/output in the BS2. Not sure if this helps

If you need a simpler version, then you can simplify what you've already posted. If you want us to rewrite the program for you, I don't think so.
What you said you want to do is very simple. You need to go through the tutorials for learning about the Stamp and Parallax Basic. These are "What's a Microcontroller?" and the "BASIC Stamp Syntax and Reference Manual".

Look under "BASIC Stamp Documentation" and under "Stamps in Class Downloads".
