Options│Save As leads to the Save Options dialog box, where Borland Pascal saves settings you have made in the Search dialog boxes (both Search│Find and Search│Replace), in the Compile│Primary File commands, and all the settings under the Options menu.

All options and the editor command table are stored in the options file; history lists, the desktop state, and breakpoint locations are stored in TURBO.DSK, TPX.DSK or BP.DSK, the default desktop file.

When you start Borland Pascal, it looks in the current directory for the saved option file. If it doesn't find the file there, it looks for it in the Borland Pascal directory (where TURBO.EXE or BP.EXE is run from).
