/* MCS is the main filesystem on CASIO calculators. They contain settings,
|
|
* programs, lists, pictures, captures, matrixes, and other data CASIO
|
|
* calculators own. This format is common to fx and fx-CG MCS archives.
|
|
*
|
|
* Keep in mind that all numbers in the MCS format are BCD-encoded.
|
|
* Because of some precision issue (0.3), we'll deliver them to the user
|
|
* almost as is.
|
|
*
|
|
* MCS files have a group, a directory, a name and a type. This type depends
|
|
* on the group it's in. So for example, the 0xFE type in the 'S-SHEET' group
|
|
* will correspond to a spreadsheet! In an MCS std. file, files are more or
|
|
* less regrouped by their group (but sometimes they're not, there are several
|
|
* 'PROGRAM' groups with one element for example).
|
|
*
|
|
* The `number` field in the Standard Header corresponds to the total number
|
|
* of MCS files, not group instances!
|
|
*
|
|
* Each group instance have a header, and here it is: */
