I am using a 4x4 matrix keypad and I'm trying to store an input from the keypad subroutine for use in a password checker. I have the keypad working and have a password checker that works using the Debug window.

My question is what command or series of commands is necessary to store the input from one subroutine and use it in another?

My keypad is connected via P0 through P7 with the use of 220 ohm shock resistors and 10K ohm pullups...

Please do not post the same message in more than one forum. Since you started in the Stamps in Class forum, you should continue there.

sorry... I noticed this forum seems to get used more frequently after the original post and thought I would try both.
