Paul,

according to the Stamp Manual PUT and GET are used to write to or read from Scratch Pad RAM.

Since I have never used a Stamp I don't know what the Scratch Pad RAM looks like. (The PIC doesn't have any)

I would guess they have a chip on board (1wire or I2C) that has a few bytes of RAM. And those "special" commands are used to access that memory.

I think there is no direct replacement for those commands, as the PICs internal Memory is handeled differently.

But I'm sure if you would post a code example we would be able to help.
