 *     Specification for the DataWorkSheet clipboard format
 *		
 *     Chao Ping Yang,  11/8/90
 *
 *     This format is used between Origin and a DDE client for
 *     real time transfer of DDE data.
 *     It is a more efficient alternative to the CF_TEXT 
 *     format
 *
 * revised 10/26/93 to add DDE_DATA_LPSTR
 * revised 8/24/94, add msc check for the DataWorksheet def
