| Event wrapper | Event driven subroutine associated to a screen or rule-set |
Screens are developed, and compiled based on the parameters found in the Screen dictionary for the corresponding file.
Screens, are driven by the “overlying” logic which is embedded in the Screen dictionary, and the underlying logic contained within subroutines attached to screens or rule-sets.
The "overlying" logic includes input and output conversion and masking, Validation, Help messages, Translates from other files, pop- up window selection criteria and associated display fields, where to call “other subroutines”.
