position continues at the beginning of the previously defined file source.

<FileSource line> and
<EndFileSource line>. The FileSource line parameter becomes the data file name.
The following line specifies the data file’s characteristics. All of the following com-
mands can be omitted.
SourceType
Specify one of the following types to the parameter:
MONO_A
Data is ADPCM at mono_level A.
MONO_B
Data is ADPCM at mono_level B.
MONO_C
Data is ADPCM at mono_level C.
STEREO_A
Data is ADPCM at stereo_level A.
STEREO_B
