|

| 4 | ;
|
|---|
| 5 | ; Deal with impossible errors (errors which should never occur,
|
|---|
| 6 | ; and which weren't already trapped by M).
|
|---|
| 7 | ;
|
|---|
| 8 | IMPOSS(UETYPE,UEOPT,UEMSG,UEMSG2,UELOC,UEROU,UENOLOG) ;EP - deal with impossible errors - called from many places
|

| 9 | ; $$IMPOSS^BPSOSUE(UETYPE,UEOPT,UEMSG,UELOC,UEROU)
|
|---|
| 10 | ; UETYPE = kinds of problems which may have occured
|
|---|
| 11 | ; ["FM" a Fileman call has returned an error
|
|---|
| 12 | ; ["L" a LOCK with ample time has failed
|
|---|
| 13 | ; ["DB" a database error (some missing/incorrect field)
|
|---|
| 14 | ; ["P" a programming error / some unexpected condition
|
|---|
| 15 | ; ["DEV" some kind of device or file error
|
|---|
| 16 | ; UEOPT = options available; first one listed is the default
|
|---|
| 17 | ; Defaults to "TRI"
|
|---|
| 18 | ; ["R" retry - retry the operation; log err
|
|---|
| 19 | ; ["I" ignore - continue as though operation had succeeded; log err
|
|---|
| 20 | ; ["T" abort - log err and terminate
|
|---|
| 21 | ; UEMSG = optionally, an additional message to output
|
|---|
| 22 | ; can be .MSG, and we'll walk the array for you.
|
|---|
| 23 | ; UEMSG2 = even more message, like UEMSG. In a Fileman call failure,
|
|---|
| 24 | ; you'd probably send .FDA,.MSG
|
|---|
| 25 | ; UELOC = location, any number or name unique to the calling routine
|
|---|
| 26 | ; UEROU = the name of the calling routine
|
|---|
| 27 | ; UENOLOG = true if you do not want error log entry to be made
|
|---|
| 28 | ;
|
|---|
| 29 | ; $$ returns 1 to retry, 0 to ignore
|
|---|
| 30 | ;
|
|---|
| 31 | ; Caller may do with these values what he desires.
|
|---|
| 32 | ;
|
|---|
| 33 | ; To prevent excessive errors, we won't actually log an error if
|
|---|
| 34 | ; another one has been logged recently.
|
|---|
| 35 | ;
|
|---|
| 36 | ; This routine really isn't as important as it looks. In fact,
|
|---|
| 37 | ; it will almost never be encountered in practice. Its existence
|
|---|
| 38 | ; owes mostly to an outrageous ruling made in the name of,
|
|---|
| 39 | ; but contrary to, the very quality and maintainability that forced
|
|---|
| 40 | ; errors give you. This in turn led to a significant delay
|
|---|
| 41 | ; in the release of a product which has been proven to be dependable
|
|---|
| 42 | ; in practice.
|
|---|
| 43 | ;
|
|---|
| 44 | ; Formerly, a zero/zero forced error was found at various places
|
|---|
| 45 | ; in the code. In 13 months at ANMC, 11 months at Sitka,
|
|---|
| 46 | ; and several months at Pawhuska, Wewoka, Santa Fe, and Taos, the
|
|---|
| 47 | ; zero div by zero traps were never encountered, but over $3,000,000
|
|---|
| 48 | ; in revenues were collected. The ironic thing is,
|
|---|
| 49 | ; without those extra checking, of things like Fileman return values,
|
|---|
| 50 | ; sanity checks on input values, etc., the product would have been
|
|---|
| 51 | ; less reliable, yet it would have sailed through the verifiction
|
|---|
| 52 | ; phase of the project plan.
|
|---|
| 53 | ;
|
|---|
| 54 | ; Forced errors already pervade all of the M language. <UNDEF> is
|
|---|
| 55 | ; a forced error, for example. And forced errors are an integral part
|
|---|
| 56 | ; of the design of the very hardware that runs these programs.
|
|---|
| 57 | ; Follow the anti-forced error policy to its logical end and you
|
|---|
| 58 | ; go to Intersleaze and say "stop issuing <UNDEF> and instead,
|
|---|
| 59 | ; prompt the user for the opportunity to continue" and then you go
|
|---|
| 60 | ; to Intel and say "remove the addressing exception trap from your
|
|---|
| 61 | ; microcode; our support organization wouldn't be able to cope with
|
|---|
| 62 | ; the problem report on something like that."
