Look at the following journal, it looks straight forward:
; IDL Version 3.6.1b (windows 3.1)
; Journal File for user@DOS Host
; Working directory: D:\IDL
; Date: Fri Dec 16 17:39:00 1994

a = 123b
b = 1b
print, a and b
; 1
print, a and 2b
; 2
c = string(a, format='(z2)')
print, c
;7b
print, a and 4b
; 0
print, a or 4b
; 127
print, a xor 4b
; 127
print, a xor 2b
; 121
