!PrimeChek  1.03 (08 Aug 2005)
==========

This program will tell you whether a number is Prime or not.  At present it is limited to numbers with upto 73 digits.

Once you have entered the number, the checking is started by either pressing <Return> or clicking the OK icon.  If the checking process seems to be taking too long, pressing <Escape> will halt it.

For those of you who are interested in such things, the checking for numbers upto the RISC OS Basic integer limit (2147483647) is done with standard integer maths in Basic.  Above this number, routines from Nick Craig-Wood's Numbers module (as updated by Gavin Wraith) are used.

To download a copy of the Numbers module with some examples go to:

This program was produced using Dr Wimp.  <http://www.rayfavre.me.uk/>

Subject to the conditions for distribution of the Dr Wimp library and the Numbers module, PrimeChek is released as freeware.
