Verbs

ASYNC
specifies an asynchronous type panel display. Asynchronous requests result
in the immediate return of control to the NCL process, with input arrival being
notified through INTREAD.
SYNC
specifies a synchronous-type panel display. Synchronous requests display the
panel, and the NCL procedure then waits until either the user operates a
function key or a timeout period elapses. The timeout period is set by the
NCL panel control statement #OPT INWAIT operand. If this operand is not
specified, the procedure waits indefinitely for input.
Note For more information on panel control see Section 6, “Panel Control Statements.” See also the panel
options under the CONTROL verb in this section.
Considerations
Before a required panel can be used, it must be defined in a panel description file
in a panel library. The order of the search path that an NCL process uses to search
for any panel description file is:
1. User panel library, the name of which is defined in your user ID definition
record
2. System panel library, which includes the following:
a. Customized panel library, the location of which is defined in the NonStop
NET/MASTER MS configuration file using the PARAM PNLCUSTSRC
command
b. Distribution panel library, the location of which is defined in the NonStop
NET/MASTER MS configuration file using the PARAM PNLDISTSRC
command
3. An installation-wide panel object library
Note User Management Services (UMS) sets up the user panel library. For details on how to set up
installation-wide libraries, refer to the PARAM command in the NonStop NET/MASTER MS Command
Reference Manual.
Frequently used panels can be preloaded into memory to avoid unnecessary
library searches.
Note For information on preloading and unloading panels using the PPRELOAD and PUNLOAD commands,
refer to the NonStop NET/MASTER MS Command Reference Manual.
