I just received my TC++ pro materials last week. And while I am fairly impressed with it, I have had one "accident" that I want to tell others about. It suggests two problems. My system: Model 70 (20mhz 386), PC DOS 4.01, QEMM.SYS 4.2. I had been working for some time on a C file, but hadn't done the usual archiving I do every few hours. I pressed F2 (save file) and wham! -- a big hard crash with: 110 ??? in the upper left corner of the display (I'd experienced this once earlier that day while debugging within the IDE). Aside from the usual "Oh! I *hate* that!" reaction, I wasn't worried: I'd expe- rienced this often with WordPerfect 5.1 *before* WPCorp. modified WP to work around *problematic EMS drivers*. First problem: if this is the same problem WPC had, watch out for TC and the 4.2 version of QEMM.SYS. Probably the real problem is QEMM.SYS, not TC.EXE. N.B.: QEMM.SYS passes the emstest.com testing program no sweat. These crashes were ut- terly random, just as they'd been when WP had problems. The more important problem: When I rebooted, the file I'd been editing had been truncated to 0 length as though TC (re)created the file and was about to write its editor buffer when the crash occurred. TC apparently doesn't take the safe approach: write a temp file and when safely done delete the old version and rename the new. My lesson: turn "editor backup" ON! -- Frank Burleigh burleigh@cica.cica.indiana.edu USENET: ...rutgers!iuvax!cica!burleigh BITNET: BURLEIGH@IUBACS.BITNET Department of Sociology, Indiana University, Bloomington, Indiana 47405
