Since I posted my last article I have been wondering
about T/Sedit and how to integrate it into the OS-9
system disk.
Does anyone out in net-land know if T/Sedit can
be put on the OS-9 system disk so that when 'edit'
is called, T/Sedit would run instead of the line
editor that comes with OS-9 ?
Maybe it could be renamed to 'vi'. I would appriciate
it any comments on this subject. Thanks in advance.

I think that by removing edit from the disk and renaming TSEdit as edit, you should have no problems. I have tried to use TSEdit with FHL OPAK with little success, it seems that they conflict with each other. > Does anyone out in net-land know if T/Sedit can > be put on the OS-9 system disk so that when 'edit' > is called, T/Sedit would run instead of the line > editor that comes with OS-9 ? > See above. > Maybe it could be renamed to 'vi'.

One thing you could do is to change the name of the module; you could do this with the debugger. If the name is "tsedit" (or anything else longer than "edit") it's easy; otherwise you'll have to either extend the module at the end or move things about. Eh? you say. OK: look in the docs for the layout of modules. One of the standard things in the module header is "offset to name of module." You need to look into the module at that offset, and there you'll find the name tsedit currently goes by. Let's suppose it's "tsedit" (I hope that's a safe assumption). You'll note that the trailing "t" has its sign bit set; that's how end of string is recognized in quite a few places in OS-9. OK. Now, come to think of it, there are two ways you can proceed: 1. Increment the offset by two (skipping over the "ts" in "tsedit"!). 2. Leave the offset alone and change the name string. Take your pick; either should do. Once you have that done and saved, you will have to update the module checksum, since OS-9 won't let you load it otherwise. You can do this with the "verify" program, I believe. Then, move the file containing your newly-CRCed module into your current execution directory under the name of "edit" and you're ready to go. (Do work on a copy of tsedit, in case I've made a mistake somewhere.) Welcoming corrections if needed, James Jones
