Three questions for the folks of netland: 1) Having just rearranged my apartment a bit, I find my microwave is now very close to my system unit. Question is, can the output of the microwave have an adverse effect on my data/hardware? 2) I asked about this before, but it was a while ago, and I did not get a reply so I figured I would inquire again. Several months ago, somebody mentioned a __video structure used internally by TC which when tweaked in the proper way allowed for even faster video output than DIRECTVIDEO alone. Could somebody post/email me this info? 3) Couple weeks ago I asked for some C code which would enable me to set and retrieve the current switchar. I received several responses (thanks to all!) and they work quite nicely. Thing is, I can't really seem to see what the use is; even with my disk-manager software in use and switchar set to '/', things work fine. (the disk manager is homebrew, written in TC1.0/1.5/2.0) I didn't do any extensive testing, but things all seem to work fine no matter what switchar is set to. So could somebody post a write up of why you would change it, how it can be a problem, and so on. Enquiring minds want to know....

Use of switchar other than '/' breaks some programs, notably Norton Utilities. Fred Sullivan SUNY at Binghamton Dept. Math.

If you search for the byte sequence B80037CD2180FA2F7405 ^^ and change the indicated 74h to EBh (changes a JZ instruction to JMP), Norton utilities will function correctly with an altered switchar. This sequence is found in every one of the utilities, and has been the same since version 3 at least. Keep in mind that although NORTON.EXE functions when patched, it cannot find it's help file unless the path is built using the backslash ('\'). -J. --- John P.
