The 'modified' property

Boolean scalar

Valid for: OLEContainer (Implemented under Windows only)

The modified property is set to 1 whenever a document in an OLEContainer control is modified by the user. You can set it back to 0, in which case it will remain 0 until the document is modified again.

The main purpose of this property is to indicate to your program that it is necessary save the contents of the document in a file (you can do this by reading the contents property and writing it out either to a native file or an APL component file).
