[Coco] Back to DEF FN

[Arthur Flexser]

Rogelio,

That's because you defined a function that only involves what to the
function is considered constants, that is, non-arguments.

If you'd defined the function as FNRE(A)=X-INT(X/Y)*Y+A, and then set some
variable Q equal to 3 and printed FNRE(Q), you'd get the value of X mod Y
with 3 added to it.
