Examining the output

When a GAMS file is run then GAMS in turn creates a LST file of problem results.  One can edit the LST file in either the IDE or with a text editor to find any error messages, solution output, report writing displays etc.  In turn one can also reedit the GMS file if there were need to fix anything or alter the model contents and rerun with GAMS until a satisfactory result is attained.  Now let us review the potential elements of the LST file.
