Yes. PARSAV,ALL,fname,ext saves the parameters and arrays to an external file. It can be issued after each solution, but it does not recognize any select logic so you need to delete any arrays that you do not want to be written to the file (see *DEL command). You need to use different array and filenames for each solution and use PARSAV to save the data for each solution. In the final solution before issuing the solve command, issue multiple PARRES,CHANGE,fname,ext commands to read the array data from each of the previous solutions. NOTE: the CHANGE option completely replaces all values for any array on the file.
