DEFINELIST Procedure
For tributary stations, this parameter has no functional effect; a dummy argument
must still be supplied, however, for each station except Envoy’s multipoint tributary.
In this case, the
polling-type can be:
0 RVI (reverse interrupt)
1 WACK (wait for acknowledgment)
2 NAK (negative acknowledge)
Condition Code Settings
< (CCL) indicates that an error occurred (call FILE_GETINFO_ or FILEINFO).
= (CCE) indicates that the DEFINELIST procedure was executed successfully.
> (CCG) does not return from DEFINELIST.
Considerations
Call DEFINELIST after the call to FILE_OPEN_ or OPEN but before the first call to
READ or WRITE.
