Options

The Options dialog can be displayed by pressing Ctrl+O, and allows to define the following parameters:

Lapses - requested forgetting index, i.e., proportion of items that are allowed to be forgotten at repetitions (this value may vary from 3 to 20%).

Directories - used by SuperMemo (database, configuration, help and text files).

Word-wrapping - request for the item editor to wrap items within the displayed area. Note, that word-wrapped items are not compatible with SuperMemo 6 for DOS.

Date format - date format (UK: DD.MM.YY or US: MM.DD.YY).

Text editor - text editor used by View text files and in other contexts of SuperMemo (Windows Notepad by default).

Graphic editor - graphic editor used to edit images associated with items (Windows Paintbrush by default).

Sound editor - sound editor used to edit and record sound files associated with items (Windows Sound Recorder by default).

Spell-Pad - request for the spelling drills during repetitions (Spell-Pad is activated only if the Spell-Pad string is part of the item)

Audiovisual file access mode - location and names of wave and bitmap files. The following modes are available: (1) Standard - files have the same names as the database and are kept in the database directory, (2) Linked - files are taken from another database that uses Standard file access mode, (3) CD-ROM - files are taken from a CD-ROM directory tree, and (4) CD-ROM Alias - files are taken from locations specified by the PTR file of pointers to a CD-ROM directory tree).

Options also allows you to Write parameters to the disk, Read parameters from the disk, and to restore Default parameters of the program.

The Lapses parameter makes it possible to specify the requested value of the forgetting index, i.e., the proportion of items that are not to be remembered at repetitions. The permitted range of Lapses is from 3% to 20%. For Lapses equal 3%, the learning process will proceed 5-10 times slower than for Lapses equal 20% (esp in initial months). However, the knowledge retention will be as high as 99%! For Lapses equal 20%, learning may be quite fast, but retention may drop even below 90%. High values of Lapses should not be used for highly interdependent knowledge structures. Moreover, low retention can render some of the items extremely elusive, if not completely intractable. Such items must be deleted, or the learning process will grind to a halt (no visible reduction of the Burden parameter over a longer time, even if the Interval value increases substantially). The recommended value of Lapses is 5-10%. Upon using the Lapses option, the Approximate procedure should be used to adjust the OF matrix to the new RF matrix setting.
Note! The longer you use your database, the longer it takes for the measured forgetting index to approach the requested value.

The directories used by SuperMemo may be set by means of the Options dialog box:

Database path - path to a directory in which database files are kept (used by Open). The default value is the current or working directory.

SM7.INI path - path to a directory in which SM7.INI file is kept (used by Read and Write parameters). The default is the directory from which SM7.EXE has been run.

Text file path - path to a directory in which info files installed with SuperMemo are stored.

Help path - Path to a directory in which the help file is kept (used by Help). The default is the current or working directory.

The Date format option of the Options dialog allows you to change the format in which dates are displayed or input from the keyboard. The two formats are:

days - months - years (UK)

months - days - years (US)

If you want to make option settings permanent, choose Write. This command button in the Options dialog allows to store the parameter set on the disk. Options are stored in the SM7.INI file which is kept in the directory specified by Miscellaneous : Options : SM7.INI path. Note, that some parameters are related to the currently opened database. These parameters are stored in the database INI file.

Options : Read can be used to read the parameter set from the SM7.INI file. The initial parameter set is loaded from the SM7.INI file when you run SM7.EXE. This file is taken from the same directory from which SM7.EXE has been run
