obj = dt << Compare Data Tables(
Compare With( Data Table ("Data Table Name"));
For example, to compare the data tables Students1.jmp and
Students2.jmp, proceed as follows:
dt = Open( "$SAMPLE_DATA/Students1.jmp" );
dt2 = Open( "$SAMPLE_DATA/Students2.jmp" );
obj = dt << Compare Data Tables( Compare With( Data Table( "Students2" ) ) );
mtx = ( obj << Get Difference Summary Matrix );
