Where is my output?

LOG and LST files

When GAMS runs an output file is automatically generated.  That output file has the file extension LST.  The first part of the LST file name is the first part of the name of the GAMS input file.  Thus, if the file myfile.gms is the file run through GAMS the output will be on myfile.LST.  This output file is an ASCII text file in the courier font that can be loaded into a text editor. GAMS also generates a LXI file (in this case myfile.LXI that contains navigation information that is used by the IDE in moving generating the navigation window that permits around the LST file.

Output also appears on the LOG file particularly if one is using the IDE.  That output summarizes the run results and also can serve as a navigation aid when using the IDE.  The LOG file does contain information relevant to the solution and error status.  It is named using the same practice as with the LST file but the file extension is LOG i.e. myfile.LOG.  It also is reproduced in the process window of the IDE.
