Episode over. Naturally he ignored my demand for payment of my collection efforts. He hasn't learned anything. Probably never will.

O thats a good one. All the emails go right to the detectives from this email anyway so i doubt i would get scammed from anyone. Anyway have a good life and hope your internet cafe goes good.

Well, now I'm back to work. Found out how to use binfmt_misc today, the Linux module (or builtin feature) that allows you to tell the kernel how to handle files based either on the magic number (good) or extension (Windows-style, Bad). Here's my rc.binfmt_misc startup file, and the postscript program that functions as a filter (command-line utility) using ghostscript as an interpreter, through the binfmt_misc mechanism. All this was to serve as a test for btoa.pf, the ASCII-85 encoder written in postforth. After setting my environment variables, I could run the script successfully:

If anybody's tried, you can see I've already broken postforth again, I think when changing stack size in the kernel yesterday. I never did like the messy way I create the return stack in postforth v0 anyway. But I played with it till it at least compiles pf, which is what is necessary to run btoa.pf. Now to see if I can get the CD burner working before the night is over.
