When we asked Jack, if it is possible to release the ABC-Compiler alone ... we pointed out, that it is uninteresting for a pure-basic-coder, to buy the whole development CD only to receive the compiler.
Jack seems not convinced of this idea because he belived, that there is not much interest in a "ABC-only CD" - he was surprised, that all 4 of us were very interested . Jack than mentioned, that there is a second problem: some manual / docs (don t know exactly wich) have been lost and he would not release a "unsupported" product. Gregor explained, that he has a paper-version of the missing manual and is willing to create a file of it ... so Jack finally changed his opinion. I do not know exactly if Gregor really made this file and if it is different to the file you mentioned. I just was happy to see, that Jack picked up our idea.
We asked Paul at the RISCOS-Expo (NL), why not releasing the ABC-Compiler alone. He told us, that he did not expect a big interest in that and that the manual-file was lost. One german user (Gregor Gelissen) explained, that he was willing to make a new file from a old paper-hardcopy. So if there is a manual-file for the ABC-Compiler on the CD, we have to thank Gregor, who made it possible. Anyway - nice to see, that user-suggestions are taken serious. Well done Castle!
