Alternatively
disp int(entry(1,string(decnum),".")) int(entry(2,string(decnum),".")).
should work.
disp int(entry(1,string(decnum),SESSION:NUMERIC-DECIMAL-POINT)) int(entry(2,string(decnum),SESSION:NUMERIC-DECIMAL-POINT)).
disp int(entry(1,string(decnum),SESSION:NUMERIC-DECIMAL-POINT)) int(if num-entries( string( decnum ), session:numeric-point ) = 2 then entry(2,string(decnum),SESSION:NUMERIC-DECIMAL-POINT) else 0 ).
