Clearing Ram

Archiver

Hello,

I'm switching between program banks for the first time, and I'm wondering if
there is an easy way to clear all the variable space ram to 0 so I can start
fresh when the program switches over?

Thanks,
stewart

This little routine takes advantage of the Stamp's flexibility with memory
indexing.

ram VAR Word

FOR ram = 1 TO 12
ram(ram) = 0
NEXT
ram = 0

Glad you like it. After sending the message, I thought that a small change
would be a good idea. Here's the updated version:

ram VAR W0

FOR ram = 1 TO 12
ram(ram) = 0
NEXT
ram = 0

The other version of the program could give you grief if there was a word
variable defined before "ram." By using aliasing of the internal variable
name W0, this new version is guaranteed to work, no matter what other
variables you have defined or in what order.
