eq

Top two items are popped from the stack and compared for equality. 0 or 1 is pushed back to the stack where 1 indicates equal and 0 (zero) ndicates not equal

the equal/not equal evaluation can also be performed with “true” (1) and false(0), respectively.

if (1 eq (1))
    trace("1 is equal to 1")
endif
 
#  alternate example
 
1 dup eq
if true
  trace ("one is always one")
endif
