FldModified

This property will return 1 if the entry text or attached data field has been modified by the user and 0 if it has not been modified. If the property returns 1 this would generally mean the user has entered data into the object at runtime.

NOTE: This is a runtime only property and will not show up in the object inspector. The value of this property would be retrieved using the GET_OBJ_PROP() function.

NOTE: In the case of the TTASMemo this property works a little differently. Each time the user enters the object, the object makes a copy of what's presently there. Then, if you access this property, the stored version is compared to the current value. If it's different this property returns True, if not, it returns False. When the user enters the object the next time a copy will again be made and that will be compared when this property is checked. Also, when you check this property, if the field has been changed, and there is an attached field (FieldName above other than NONE), that field will be updated at the same time.
