-The special case of '''gcd(0,0)''' is usually defined to be '''0''', but some authors consider it to be '''undefined'''. When implementing the REXX version 1 example, the first definition (equal to zero) was chosen.  So, for that case, '''|0| = 0'''.

-It is useful to define gcd(0,0)=0 and lcm(0,0)=0 because then the natural numbers become a complete distributive lattice with gcd as meet and lcm as join operation.
