// *** ---------------------------------------------------------------------***
// Function: CMD_SetIndex
// Purpose: Sets the autoincrementing Index for MODIFY_CMD
// Parameters:
// IN int nIndex - Index value 0 - 15
// IN DNHANDLE DnloadID - Effect ID in stick

// Returns: SUCCESS if successful command sent, else
// SFERR_INVALID_OBJECT
// SFERR_NO_SUPPORT
// SFERR_INVALID_PARAM
// Algorithm:
