Memory Use Reduction in GAMS

Memory usage by a GAMS program is often a function of the implementation.  Code can often be changed so memory requirements are reduced without substantively altering the bottom line results of the program.  For example, I have seen substantial reductions in memory requirements achieved by rewriting a small amount of GAMS code without changing results.  Here I cover

I limit coverage to the memory usage within GAMS not covering manipulations to reduce memory use within a solver called by GAMS.
