Echelon Neuron - Manual (Page 173)

This example causes 13 bytes of zeroes to be pushed onto the data stack.
push #d’13 ; (13)
call _alloc ; (0(13))
_and16 (And, 16 Bit)
This function returns the bitwise AND of two 16-bit values.
Stack Transformation: (a(2), b(2) -- a(2) & b(2))
Location: Near
Registers Affected: None
Example:
This example performs the operation h’1234 AND h’4321.
pushd #h’1234 ; (h’34, h’12)
pushd #h’4321 ; (h,21, h’43, h’34, h’12)
call _and16 ; (h’20, h’02)
_dealloc (Deallocate Stack Space and Return)
This function removes N items from the stack and returns to the caller of the
caller of this function. Consider using the DEALLOC instruction for N less than
9. Also, consider using the _drop_n function to deallocate local variables and
returning to the calling function.
Stack Transformation: (value, a, b, c, … -- )
Location: Near
Registers Affected: None
Example:
This example drops 13 bytes from the stack and returns to the caller of
LocalFunction.
callr LocalFunction
; _dealloc returns here.
LocalFunction
push #d’13 ; (13, a, b, c, …, m)
call _dealloc ; ()
_dec16 (Decrement, 16 Bit)
This function decrements a 16-bit value by 1.
