A dynamic model building system using virtual memory.

A self-contained model building and storage managements system written entirely in FORTRAN IV (at IBM G level) is described. The objectives of this system are a.o.:1) To provide variably dimensioned arrays, specified at run time. To provide dynamic reallocation of storage to allow the user to work in a large virtual core.3) To provide archiving, check pointing, and restart procedures.4) To operate as a control system.
