Overview
The MDL file is the file used to generate a RAD window. This file contains the entire description of the pattern to generate. This description is made of two distinct parts:
  • the description of the pattern,
  • the description of the window.
This help page only presents the code used to describe the window. To present this code in details, the script of a Form.mdl pattern is used.
CAUTION: In version 12, the RAD was entirely rebuilt. The MDL files are kept for backward compatibility. See New RAD patterns for more details.
