When a DISPLAY service is issued, the )INIT section is processed before the panel is displayed on the screen. Each time you scroll and the panel is redisplayed, the )PROC and )REINIT sections are not processed. The )PROC section is only processed when the panel is submitted for processing as when the Enter or End key is pressed.

When panel processing is complete and ISPF returns control to the dialog, it is possible that required fields were not displayed. Therefore, unless a VER NB was coded in the panel for a required field, it is possible that the application user never scrolled the panel to see the field. It is your responsibility to ensure that all required information is obtained.

When fields are displayed on a panel, their characteristics can change without the user interacting with the fields. For example, when CAPS(ON) is set for a field, this only affects fields that actually are displayed. If a field is initialized with lowercase letters and it appears on a portion of the panel that is never displayed, the data remains in lowercase even if CAPS(ON) was set for the field.
