Change History (most recent first):
<8> 7/30/91 JL Updated Copyright.
<7> 1/29/91 JL C++ requires midiToolNum to be a #define if it's going to be
used in the Inlines.
<6> 1/27/91 LN Checked in Database generate file from DSG.
<4> 11/28/90 JL Put formal parameter names back.
<3> 11/7/90 JL Changed all #defines to anonymous enums
<2> 11/4/90 dba used constStr255Parameter; got rid of erroneous const on some
Str255 parameters that were output strings; got rid of some
extraneous parameter names
