At the beginning part of Consau, PreType.dat is read into
an array as the following C pseudo-code shows:
byte Styles[219];
dataFile = fopen( " PreType.dat", "rb" );
fread(Styles, byte, 219, dataFile);
Now, we can get the style index of any legal segment by
merely accessing array Styles. For example, in Figure 4(a),
segment M2 corresponds to integer 3, so, the style index of
M2 is Styles[3].
