DISCARD_MODEL ​

DISCARD_MODEL removes a model that has previously been loaded with <LOAD_MODEL> from the core.

Syntax ​

leo-grammar
CC "Core" DISCARD_MODEL modelid:idValue

#-->RESULT ecode:intValue

Parameters ​

  • modelid (idValue) - the id of the model that should be loaded

Returns ​

  • ecode (intValue) - Contains the error code or is 0 in case of success.

Details ​

All changes that have been made to the model since it was loaded are lost unless they are saved to the database with <SAVE_MODEL> prior to calling DISCARD_MODEL.

Every model which is created or loaded via the "Core" MessagePort has to be discarded using DISCARD_MODEL or opened in the model editor with CREATE_WINDOW_FOR_LOADED_MODEL. If it is not discarded, the user will not be able to open it later in the model editor.

Models that have been opened in the model editor must not be closed with the DISCARD_MODEL command. Use the "Modeling" MessagePort command CLOSE instead.
