For most things, such as the number and size of variables and routines,
there is no hard-coded limit. You will just run out of memory
at some point. Judith's IDE is well over 100,000 lines of code,
and I don't hear complaints about it running out of memory.

2.4 and earlier had a limit on the length of one line of source 
(200 characters) but that limit was removed in 2.5, when the 
front-end was rewritten in Euphoria instead of C.

There's also a limit on the number of simultaneously open files
(20 or so), but without that limit you'd quickly run into the
operating system limit.

I can't think of any other significant limits off the top of my head.
I don't know of anyone who is being severely constrained by running into
a limit. I suppose there are a few other limits, but they are insanely high.
