As you know that vDos and vDos-lfn 2016.06.01 has been released recently. In previous versions of vDos or vDosXy, the setting "LPT4=CLIP" only works one-way, i.e. to copy the content of the specified file to LPT4 as clipboard (via a command similar to "COPY FILE LPT4"). However, in vDos and vDos-lfn 2016.06.01, with "LPT4=CLIP" you are also able to copy in the opposite direction, i.e. to paste the content of the clipboard (designated LPT4) to a specified file (via a command similar to "COPY LPT4 FILE"). In initial release of vDos 2016.06.01 there was a bug which caused the original direction not to work, but this has been fixed by now. Thus, with the latest vDos-lfn build 2016.06.03, you are able to both copy to and paste from the clipboard using the COPY command when "LPT4=CLIP" is enabled in config.txt. This will be even more convenient for users who like the "LPT4=CLIP" feature. As usual, the latest build of vDos-lfn is downloadable from
