We may be disagreeing no what is large and what is small.
But Rebol does have some limitations that can trip you up very early on. I
know some of these are being relieved (e.g. IOS link doubles the number of
available variables) but even so, 8000 (the IOS limit) is not enough.
Try these three snippets (you'll need a new console after the first one) to
find the fundamental limits on your machine: (the third may run for hours in
a machine with insufficient real memory. It only takes moments with 384k).
;; -----------------------
;; Maximum different variable names
print length? first system/words
nn: 1
print mold disarm try [
forever [
to-word join "Var" nn
nn: nn + 1
] ; forever
] ; try
print length? first system/words
;; -----------------------
;; maxium stack depth
recur: func [nn [integer!]] [prin [nn " "] recur nn + 1]
recur 1
;; -----------------------
;; maximum memory (or block size)
print system/stats ;; memory in use
nn: ["X"]
print mold disarm try [
forever [
append nn nn ;; double the length
print [now/time/precise length? nn]
] ; forever
] ; try
print system/stats
