When working with compiled project applications, keep in mind that commands that save lists to the structure, such as ARRAY TO LIST, will have no effect because the compiled structure (.4DZ) is read-only. In this scenario, it is recommended to save lists to locations that are not in the structure file. For example, a list can be converted to a BLOB using LIST TO BLOB. Then, the BLOB can be saved to the data file. The list can later be retrieved using BLOB to list.
