    } pets;
} Ppick_data3;

Because this function returns information on the default pick data (PET 1), the data structures for the other PETs have been omitted.

Description

pinq_def_pick_data3 queries the workstation description table and returns values for the following:

•List of available prompt and echo types

•Default echo volume in device coordinates

•Default pick data record
