FUNCTION: Bitwise Logical Operators AND and OR
DESCRIPTION:
The operators & and | are typically used with IF, JP, and JS to perform conditional jumps;
however, they can also be used to perform bitwise logical operations.
ARGUMENTS: n & m or n | m where
n and m are signed numbers in the range -2147483648 to 2147483647.
For IF, JP, and JS, n and m are typically the results of logical expressions such as (x > 2)
“&” is also used to pass a variable by reference in a JS call. See JS.

value=5 ;'a value to be passed by reference
global=8 ;'a global variable
JS #SUM (&value,1,2,3,4,5,6,7) ;'note first arg passed by reference
MG value ;'message out value after subroutine.
MG _JS ;'message out returned value
