OK, as a starter I'll agree I'm an old fogey, but... :) I still prefer to use the old DOS Brief editor. With some effort and the aid of a batch file to translate to/from long file names, it has continued to work for me up to and including XP under 4NT. Until, that is, just recently. After putting up w/ using other alternatives for a while, I finally spent some time today to try to get to the bottom of the issue. What I learned has me baffled as to the "why" of the symptoms. The upshot is that the two device drivers that have been in my configuration for using Brief no longer will load under 4NT. But, the strange part is the critical one (101key.drv) _WILL_ load under CMD.EXE and Brief will function as normal. Hence the question I would like ask is "Can anybody understand this difference of why the command processor would affect this?" and secondly, "Is there any possibility of any workaround?" I have not updated machines nor XP (auto update is off) for quite some time (owing primarily to being on dialup so speed is such an issue it's extremely difficult at best unless there's an absolutely mandatory need) and for the first several years I used Brief regularly as was in a heavy programming development phase where it was/is my primary tool. I then retired about two years ago and so the usage as dropped precipitously. The point is that I know it worked fine for quite a long time and this is apparently somehow related to one of the last updates I probably made in XP. If it weren't possible to load the same driver under CMD.EXE I'd probably just give it up as lost cause, but since evaluation the last two days as indicated it does work there, it seems as though there's not a fundamental limitation if one could only discover the secret... :) As part of the exploration process I thought perhaps a newer version of the JPSoft tools might resolve the problem since I hadn't upgraded since retiring. So, I downloaded both the 4NT 8.02 demo version and TCC/LE really thinking joy was in the offing, but sadly, no...identical symptoms as with my venerable 4NT 3.02. :( So, anybody have any ideas? More details, specifics, etc., on request if anybody has specifics would think useful.
