Re: infinite loop

*hival as far as I knew has no end... isn't it an infinite number?



Nope, there are no infinite numbers in computing.  And anyway, it
depends - with a 1 digit index, *HIVAL would be 9.  But as of V5R3, the
index used for no-result-field is 63 digits long - it would take an
awfully long time to count that far.(*)

If you have TRUNCNBR(*YES) on the H spec (the default), then when the
loop reaches the maximum, it would wrap around to zero again.  With
TRUNCNBR(*NO), you'd eventually get overflow.

(*) I saw somewhere that the number of atoms in the universe is 10 to
the 80th power; I imagine 10 to the 63rd power would let you at least
count all the atoms in say the solar system ...
