xxl Posted April 27, 2020 Author Share Posted April 27, 2020 unfortunately previous versions had two serious bugs. new versions I put here: https://xxl.atari.pl/xbootdos/ - works with cartridges - controls file length while saving (loading) - I removed the POINT function 2 Quote Link to comment Share on other sites More sharing options...

xxl Posted April 28, 2020 Author Share Posted April 28, 2020 - configures itself to the appropriate sector size. - no need to recompile it. - supports e.g. MyDOS (and other DOS2 file system mutations) and not only DOS 2 - allows you to save files of different lengths, not just single-sector ones - has the BINARY LOAD function, e.g. from Basic: XIO 40, # 1,0,0, "D:filename" - sets MEMLO and takes up less memory - allows you to work e.g. with Basic, Action etc. news not available in other DOS: you can place to a floppy "temporary" file with the maximum expected size and save to it, for example, a program in BASIC (loading from such a file takes into account the length of recently saved data, not the length of the entire temporary file) - which eliminates the need to create files and allows you to keep the compact DOS size which takes $130 bytes (304 bytes) = MEMLO $930 3 Quote Link to comment Share on other sites More sharing options...
