The Invoke a Process overlay is the same when you select the invoke a process option anywhere in Application Design, although the level of defaults may vary. Figure 3-3-9 below shows the overlay called from a menu process which defaults the currently selected process.
Figure 3-3-9. Invoke a Process Overlay
You can change the default values on the Invoke a Process overlay to invoke any process name or type that you choose. This overlay also contains the following option:
Run with Trace
The run with trace
option supplies you with a trace log that
itemizes everything APPX has done during the execution of
the selected process when the selected process is finished. Each line
of the trace log shows a sequence number and a description of the logged
event. The display of the trace log permits you to browse the trace in
a hierarchical fashion. Events that have additional detail are identified
by a greater than sign (>) next to the sequence number. To view
the additional detail, place the cursor on the record and select enter. To
return to a higher level, select end. Selecting the cancel 
icon
from the toolbar exits the trace
display from any level.
Use the inquire option to switch to key entry at any time; this allows you to reposition yourself to a particular sequence number. While viewing a trace log, you can also use the hidden Option 1 to view the entire trace in chronological (sequence number) order.
