The POINT:INITIAL_COMMAND parameter is a single ASCII character string (character data type) that contains an optional command string that can be read when a C3D file is opened.  This string can be up to 127 characters long and could configure the C3D application to present a particular view or perform some predetermined analysis.

This parameter does not affect any of the default C3D parameters and is completely compatible with the C3D file format.  This is a nice way to pass a command or set of commands to a program for initial configuration, analysis or simply to run a software demo function for example.

Since any application or user can access this parameter, it would be a good idea if the program that utilizes the values performed a thorough syntax checks on contents to make sure that they are correct.
