An Example of the Process Cycle
The following example demonstrates the sequence of operation for a sample process cycle. In this example, a process has one frame that has ILF routines at the Start of Frame and End of Frame event points. The frame has one image, which has ILF routines defined for the Pre-Display and Verify event points. The frame also includes one automatic child, which has ILF routines defined at the Pre-Invocation and Post Invocation event points. For each selected record in the process control file, the sequence of operation is as follows:
Read the process control file record.
Invoke the Start of Frame event point.
Perform image processing:
Invoke the Pre-Display event point.
Display the image on the screen.
User completes data entry.
Invoke the Verify event point.
Invoke the End of Frame event point.
Perform automatic child processing:
Invoke the Pre-Invocation event point.
Perform processing as specified for the child process.
Invoke the Post Invocation event point.
