Disable the standard output

During the calculation, GICO writes the description of each optical element which is computed to the output file. For systems with many elements, this can result in very large files, which contain almost identical information for each calculation. To save disk space, use the command: 3 S(ET) O(utput) <Enable or Disable> ; [example: S   O   D ;] [S   O   E ;]

to turn the output off and on again.
