It would be natural to use a Kleene star to represent an arbitrarily
long string of LONGs -- "long* int" -- though AFAIK Algol68 doesn't
do bignums. Weirdly even most 21st century progamming languages do
not provide built-in support for bignums!
C's INT_MAX, LONG_MAX etc are kind of an environment enquiry...
