Hi there,
Now I know that \input is esentillay the same as have the inputed text
actually in place in the document. But I am not too sure if there is a
memory penalty or not. In other words say I have a file of several
sections that is 2000 lines long containing a lot of PiCTeX
structures. Would it be better to input each section seperately in
terms of memory or does it make no difference at all. Lets forget
about editing and getting TeX to process the file without errors
 at the moment I am
purely interested to know how TeX manages its memory.

Does TeXs memory get cleared as each page is shipped out?

 I am using TeX 3.0 and have installed the BiG-TeX size as default.
Can it be made even bigger?

It seems that only by putting \clearpages in the document at the
moment will the document process without main memory being filled.

I am using TeX to do a lot of things, drawing structures etc, keeping
track of the numbers and the like so I suppose I am at the edge of
TeXs performance.

Comments to the above will be appreciated either by e-mail or by
posting to the Net.

Thanks in advance.
tony scott.
