* Modification Log:
|
|
* -----------------
|
|
* .01 11-11-91 jba Moved set and reset of alarm stat and sevr to macros
|
|
* .02 02-05-92 jba Changed function arguments from paddr to precord
|
|
* .03 02-28-92 jba ANSI C changes
|
|
* .04 04-10-92 jba pact now used to test for asyn processing, not status
|
|
* .05 04-18-92 jba removed process from dev init_record parms
|
|
* .06 07-15-92 jba changed VALID_ALARM to INVALID alarm
|
|
* .07 07-16-92 jba added invalid alarm fwd link test and chngd fwd lnk to macro
