I have installed the Oscat basic lib version 3.3.4.0. can anyone guide me to sort the array element in ascending order? I called the _ARRAY_SORT function in my ST program but i dont' know how to get the sorted value in my program. The ST code is : PROGRAM SORT VAR Rawdata: ARRAY[0..3] OF REAL; END_VAR OSCAT_BASIC._ARRAY_SORT(PT:= ADR(Rawdata) , SIZE:= UINT#4 );
