When running strings(1) on xdb (the screen-oriented debugger on HP-UX), I found the following: Hmmm, it seems to be in the hardware. Things look good, but you may have a halting problem. I see no bugs here. Why ask me? It's your program! I can see the problem, but it will do you good to find it yourself. You are standing at the end of a road before a small brick building... No known bugs. Hmm, seems to be in the hardware. Mice, it's mice!! There's no bug in this program. It's the operating system!! I knew, but I suffered an uncorrectable ECC error. Aha!!! It's.... no, that's not it. You don't really expect this command to work, do you? Return to sender, address unknown. SNAFU I don't know. I'd much rather play rogue. There's no bug in this program. It's the C optimizer!! Yeeecchh. This is terrible code. brain damage (mos dumped) I knew, but I suffered random alpha particle radiation. Don't press your luck....or would you like adb back!! Start from scratch. brain damage (core dumped) (mos dumped) (everything dumped) Got a dime? -- Tor Lillqvist, working, but not speaking, for the Technical Research Centre of Finland

[ a couple dozen more along the same line...] > Got a dime? In cdb(1), which evidently shares code with xdb, there is a command 'F' (yes, it's documented in the man page!) that can supposedly be used to "find and fix a bug". Try it. Does anybody know whether it is possible to invoke this command in xdb as well, or is this one other example of dead code in system software? (If so, it is hardly the first time something like that happens.

This command was removed some time ago from XDB. I guess it wasn't funny enough. :-)

I believe that these are responses given when the "f" command is given. "f" is the find and fix bugs command. Keith Marchington

Cdb is the product of a company named Third Eye Software (look for their booth at the next Uniforum near you). Cdb runs on a number of platforms besides HP. The "F" command is standard cdb. Cdb has been ported to hp-ux on the 300 series and is supported by HP (with improvements, of course). Xdb is a souped up version of cdb that runs on the 800 series. It used to have the F option. I believe the option has been removed. Larry Dwyer

The 'F' command is disabled in xdb, but FindAndFix() wasn't #ifdef'd out. That's why strings(1) will show these useful messages. BTW, this command will be going away in cdb as well. The HP folks that translate message-catalogs to non-English were pretty stymied. Management politely requested we make it a non-problem. I'm real sorry, folks. :-( ___ / / John Newman HEWLETT/hp/PACKARD Colorado Language Lab /__/ jmn@hpfcrt.fc.hp.com --------- --------- --------- --------- --------- --------- --------- ----- This response does not represent the official position of, or statement by, the Hewlett-Packard Company.

"f" is the find and fix bugs command. The "F" (find bug and fix) command has been in several debuggers. The first time I saw it was in 1983 in the AbSoft FORTRAN debugger. -- Steve Fullerton Statware, Inc. scf%statware.uucp@cs.orst.edu 260 SW Madison Ave, Suite 109 orstcs!statware!scf Corvallis, OR 97333 503/753-5382

The differences are mostly syntactic (feature sets are almost identical--i.e., cdb also has the HP-UX extensions). xdb is also available on MPE/XL.
