The and Command
The and operator combines two conditions into one, which will be true if both sides are true, and false otherwise. You can create these conditions with the relational operators =, ≠, >, ≥, <, and ≤, with functions such as 68k:isPrime(), 68k:pxlTest(), and 68k:ptTest(), or with any other expression that returns 'true' or 'false'. Other operators for dealing with conditions are 68k:or, 68k:xor, and 68k:not.
:2+2=4 and 1=0
false
:2+2=4 and 1+1=2
true
The operator can also be applied to integers, treating them as 32-bit signed integers (larger integers will be truncated to fit) expressed in binary. The bits will be matched up, and "and" will be applied to the bits individually — a bit in the result will be 1 if the two corresponding bits of the original integers were 1, and 0 otherwise.

In complicated logical expressions (both with conditions and with integers), and has greater priority than the others ("or" and "xor"). For instance:
X or Y and Z
will be interpreted as:
X or (Y and Z)
