Psion/EPOC software and resources

It appears that my ISP's server is incorrectly configured - the .tgz files are returned with the MIME type text/plain; this may cause problems on certain OSs and browsers which think that they can insert extra characters in textfiles without changing the contents...

ASM Assembler

ASM is an assembler for ARM based EPOC devices. It can save in the format used by the MC OPX.
The MC OPX allows assembled code to be loaded and executed from OPL; you cannot call the OS from assembled code, but it can be used to greatly speed up dataprocessing in OPL.
The WGFX OPX allows the pixels in a bitmap to be accessed directly from OPL or from assembled code.

To install the OPXs, simply copy the OPX and OXH files to the OPX and OPL directories in your System folder.

All of this has been developed under Linux - there is no guarentee that it'll compile under Windows.
