GET Context
GET is handled by DTASK_GET().
NAME contains the name of the required parameter. If the task is a
monolith, the parameter name must be of the form
ACTION:PARNAME to specify the particular action within the monolith.
The value of the named parameter is obtained, by searching the
vpath
if the parameter is not already active.
Note that there are some restrictions on the vpath search:
- Dynamic will usually have no effect because any
dynamic defaults will be cancelled initially and if the parameter was reset.
- Prompting is disabled so any attempt to prompt will return status
PAR__NOUSR.
The transaction is then closed (DTASK_COMSHUT()). Assuming the
status is SAI__OK, the message value of the final acknowledgement is
the parameter value as a character string. In the event of an error, error
messages are reported and the message status set appropriately.
