File Save and Read

Napier can save and read back its entire state, or selected sets of data. When the complete state is saved, it is saved as a binary file that can be used to automatically reload Napier when it is next started. If you set the Auto Save option in the Options dialog, the state will be saved when you exit Napier, and read back in when you next start it. If you force Napier to stop via the system task list, it wonít save the state.

The Start File functions, use the file defined in the Options dialog Start File section and do the entire calculator state. The other functions allow selected what data in the calculator to save and where to save it.

The Full State uses the same format as the Start File, and they can be used as Start Files. These are in a binary format that cannot be edited or used by other programs. All the other choices are saved as text files, and with the exception of Workdays can be created and edited in Embedded Word, or any other program that can work with ASCII .txt files. All files use tabs to separate the columns, and all text values must be quoted.

The reason for allowing these separate data components to be saved and read separately is to allow working on different problems which need different data. For example, you can have several different Workday schedules for different workers or systems, or different Data Sets each representing a different time series of security prices.

Workdays are text files, but the format is too complex for manual editing.

File Types

Each of these data files can have the .txt file type, which is what is needed if you want to edit them using Embedded Word. They also each have their own file type which you may want to use if you donít care about editing them, but want to keep them separated by type so itís easier to find the one you want. Both file types have the same text contents and can be used interchangeably.

If you tap Save New File, Update File, or Read File, youíll get the following dialog box which is asking you to chose which data component you want to work with:
