I tried your suggestion, twice, and each time it created a 4MB output_file, not 96 bytes.

Frankly I doubted this would work as the /x option is supposed to remove the LIF file header, but there's no mention of it stripping garbage from the end of the file.

When using DOSLINK as a virtual IL device, the file is being written by the 71B itself (COPY FILENAME TO :DOSLINK), which believes it is writing to a LIF device, hence the 256-byte 'sector' size.

As soon as you have used a command like above to copy the file, remember to CLEAR :DOSLINK, to close the output file.

I did the test using EMU71/Win and IL-Per v2.23 connected by virtual HP-IL. Results were as described, I didn't just make it up.

/X removes the header, but it also reads the header to know the proper file size to create (info stored in the LIF header). The extra 'garbage' is just irrelevant filler needed to make up the full 256-byte sector size and is removed.

Clear any existing infile.dat and outfile.dat (or whatever you may have called them) files and re-do the process closing the files after each copy and I believe you will get the suggested results.
