Chapter 3-1: Overview of APPX Processes

The Process Cycle


A single execution of an entire sequence of frames, images, event points, and children for one record in the process control file is referred to as a process cycle. For example, assume you created a process with a single frame, a single image, and one automatic child. In addition, you defined statements in Start of Frame and End of Frame, Pre-Display and Option Intercept, and Pre-Invocation and Post Invocation event points. For each record, the process cycle consists of the following APPX actions:

Read a record in the process control file.

Invoke the Start of Frame event point.

Perform image processing.

Invoke the Pre-Display event point.

Display the image to the screen.

User completes the entry.)

Invoke the Option Intercept 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 Pre-Display event point.

Invoke the Post Invocation event point.
