This statement returns data from that cache index:
Considerations
The FROM option in conjunction with the PARAM SERVERMODE option allows
workstation clients to make ServerClassSend requests to a SeeView gateway server
and in return receive large, efficiently blocked responses from virtually any HP
conversational process that the SeeView server has been scripted to allow. This
capability has a variety of applications and advantages in the area of GUI
implementations on workstations. The third example depicts this.
