| 168 | * currently being used in this instance of the structure. Fields that are |
| 169 | * always set at the same time may be numbered as a group. |
| 170 | * |
| 171 | * Instances of this structure are used in two ways. |
| 172 | * |
| 173 | * First, whenever the user's input contains a context of score, staff, or |
| 174 | * voice, a "struct MAINLL", which contains one of these structures, is |
| 175 | * allocated and put in the main linked list. For each item the user sets, |
| 176 | * the corresponding field is set in this structure and its "used" bit is |
| 177 | * set to YES. If the user sets a parameter during the course of the input for |
| 178 | * a voice, using the <<....>> construct, the SSV will be put in a TIMEDSSV |
| 179 | * structure and linked off the following BAR line. |
| 180 | * |
| 181 | * Second, a structure is allocated statically (global variable) for each |
| 182 | * possible score, staff, and voice. Each time the program scans through |
| 183 | * the main linked list, it starts off by populating the (one and only) |
| 184 | * score structure with default values for everything, and setting all its |
| 185 | * "used" bits to YES. It sets all the "used" bits for the staff and voice |
| 186 | * structures to NO. As it scans through the main linked list, whenever it |
| 187 | * finds one of these structures, it copies all the fields whose "used" bits |
| 188 | * are YES in that structure, to the appropriate fixed structure, and sets |
| 189 | * its "used" bit to YES there. The selector and linkage items are not used |
| 190 | * in these fixed structures. |
| 191 | * |
| 192 | * Whenever the program needs to know the current value of a field for a |
| 193 | * given voice, staff, and score, it uses a viewpath through the corresponding |
| 194 | * three fixed structures, in that order, using the "used" bits to see if |
| 195 | * the field is filled in. Note that the score structure is always fully |
| 196 | * populated, so the info will be found then, if not earlier. |
