Procedure CaseCommandNew


The procedure CaseCommandNew executes the same code that is behind the menu command Data-New Case in the IDE by default (please note that you can override items in the Data menu using the options listed under Project - Data manager - Using disk files and folders - Data menu overrides). If the data of the currently active case needs to be saved, a confirmation dialog box will be displayed first. Afterwards, the active case will not refer to any case file.


Return Value

The procedure returns 1 on success, or 0 if the user cancelled the operation in one of the dialog boxes. If any other error occurs, the procedure returns \(-1\) and CurrentErrorMessage will contain a proper error message.


  • This function is only applicable if the project option Data_Management_style is set to Disk_files_and_folders.

  • This function returns 0 if the IDE is not loaded, for example when running the component version of AIMMS, or when running with the command line option --as-server.

  • An alternative for calling CaseCommandNew is calling CaseFileSetCurrent with an empty string. The latter will not check whether the current case should be saved first.
