Extended BASIC assembler manual
I wanted to make use of some of the facilities of Darren Salt's module, but found the text manual difficult to follow, so I transferred the contents to a StrongHelp manual. I then realised there was scope for improving the way it was presented, so I contacted Darren and he approved. However, having sent him this version so that he could check it for correctness, he is not answering, so I am putting it here with many caveats about accuracy.
