Tr-Dos functions

Hello everyone! Here the problem arose when using function #0E (file upload), loading does not always occur :(((. The reason is not clear, under the emylem you can see that it is not PZY banks are always switched (DOS does not turn on). What's interesting is after the first download and compilation of the loader, it loads everything, but after resetting and re-compilation stops downloading. If you read the directory from Alasm again works. Attempts to use functions 01 and #18 did not lead to anything. From available sources (a couple of zx-reviews), found out that to download the file it is used tr-dos buffer, but I don’t know how to initialize it or move it somewhere. In general, you need information about the dos, what’s funniest is the function of downloading a file using it number and sector group readings work without problems. P.S. Thank you in advance for any assistance provided. Alexander

The reason is unclear, under There the download address is set in an unclear place and is buggy. It seems like there should be a download address in DE or HL and 0 in the accumulator or 3 in A and the address is taken from the catalog. Check with the doc.

It is initialized and installed in the program memory area BASIC If there is no memory there (CLEAR is too low), then there will be an error. Do this: #01, #18 when changing disk, #xx (I don’t remember) to read 16-bytes file information from the catalog and download through function 5 in blocks of no more than 16kb. I can give you a "TR-DOS disassembler" - tell me by e-mail, I'm too lazy to use t-mail. spread!

AF> and sector group readings work without problems. Hmm. Some kind of bullshit.Look at the Weclemans toy loader (version, which consists of several files), adaptation is one of the earliest, from 1992, where the files are loaded by name and always.
