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:

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.
