There is a (large) limit on the size of the "top level" code, and there
is a (large) limit on the size of any one subroutine. You can have as many
subroutines as you like however. It sounds like your huge constant
declaration caused you to exceed the limit on the "top level" code.
There's no difference between the Public Domain and the
Complete Edition in this regard.

I would recommend that you store the data in a separate data file and
read it in. You could even open() your existing file and, with some minor
modifications, read in all the numbers with a single get(). Euphoria
supports sequences with millions of elements
(provided you have enough memory).

If the numbers are all between 0 and 255 you could store one number per
byte in a file, and read them in with getc(). This would give you
a much smaller file that could be loaded much faster.
