Hi again to all devs,
Is there any way to use copybytes to take a chunk out of an array? Say, to copy elements 0-10 of an array into another buffer, then concatenate elements 20-30 onto the end of it?

what is an array? is a C array? you may want to read: http://www.mkssoftware.com/docs/man3/memcpy.3.asp and more generally a good C book
It will not work. Here is our function prototype: EXTERN void *copybytes(void *src, size_t nbytes);
The thing to see here, is that it doesn't actually copy the data to a location you specify. It creates a copy of the data, somewhere in memory, and returns a pointer to the location. If you want to have a continuous array of numbers, you'd have to copy them one at a time from one array to the other anyhow.
I suggest to just use getbytes() and for loops to do the assignment.

Ah well, that's what I've done.
