Not sure what you mean by the limitation to a "10I 0 is 65536"?
You mean the highest value it can hold?

Here are the max values for the integer types (if memory serves):
      3I 0   127
      3U 0   255
      5I 0   32767
      5U 0   65535
     10I 0   2147483647
     10U 0   4294967295

The limit for the length of an alphanumeric field with ALLOC
should be 16776704.   I suppose this might vary depending on
how much memory/disk space you have available on your system.
(Or how practical it is to load 1.5mb into a single variable)

I can't say that I've had a chance to try to push the limits
and see what happens :)
