Use this command to close the active document. QSopt suggests that you save changes to your document before you close it. If you close a document without saving, you lose all changes made since the last time you saved it. Before closing an untitled document, QSopt displays the "Save As" dialog box and suggests that you name and save the document.
If the active document is an MPS document QSopt opens a new MPS document, see New MPS command. Otherwise it opens a new LP document, see New LP command.
If the solver is currently running QSopt refuses to close the active document. If you do want to close the document you must stop the solver first, see Stop Solver command.
