Hello,

I asume that the XPT file was made with the xport engine. I guess the only way is to count the number of observations since the descriptor shows a missing value.

libname ppp xport "c:\temp\cccc.xpt";

data ppp.class; 
 set sashelp.class;
run;

proc sql;
 select count (*) from ppp.class;
 quit;

Hope that helps!

You will have to count them since the SAS v5 export format does not have any location to store the number of observations.

Either use PROC SQL or a data step with the END= option on the SET statement.
