Re: EPICS: Selecting a Text Error Message

["Schoeneburg, Bernd" <bernd.schoeneburg@desy.de>]

I have created a "strtabRecord" (string Table Record) for exactly this 
problem. It uses an externally loaded string library. The library 
contains the string tables. Each entry consists of the integer number, a 
string and an alarm severirty. If the input number is not defined in the 
table, the record will display the number instead and the alarm severity 
will be set to the predefined (UNSV). You can select a different table 
during runtime. Connecting the library works similar to the subroutine 
record. If you are interested I can send you the sources.
