So you want all of your script be compiled in a 400k executable?
Anyway, that is not the problem. Let me know if you are able to
compile the following code snippets:
my-print: print-odd: func [a] [
print [a "is odd."]
my-print: :print-even
]
print-even: func [a] [
print [a "is even."]
my-print: :print-odd
]
repeat i 5 [my-print i]
1 is odd.
2 is even.
3 is odd.
4 is even.
5 is odd.
