GAMS is used in two phases:
i.
One
uses a text editor and creates a file which contains GAMS instructions.
ii.
One
submits that file to GAMS which executes those instructions causing
calculations to be done, solvers to be used and a solution file of the
execution results to be created.
Getting started to use GAMS-IDE (GAMS with
Integrated Development Environment):
What is a project? The GAMS-IDE
employs a project for two purposes. First, the project location determines
where all saved files are placed (to place files elsewhere use the save as
dialogue) and where GAMS looks for files when executing. Second, the project saves
file names and program options associated with effort. It is recommended that
you define a new project every time you wish to change the file storage
directory (when GAMS executes a file in a different directory it will not look
for options files (*.gck), but will look in the directory where the project is
located).
blue line - opens *.lst file and
jumps to line in *.lst file corresponding to blue line in process file;
non bolded black line - opens *.lst file and jumps to location of
nearest blue line;
red line - identifies errors in
sources file by jumping to *.gms file location of error.
