GAMS Modelers sometimes have to deal with complex implementations that
| • | Use include statements to incorporate numerous files. |
| • | Have been developed by others. |
| • | Have a complex structure with definitions and uses of items widely spread in a file or files. |
| • | Contain items that are defined but never used. |
| • | Were developed some time ago but are not extensively documented. |
When faced with such cases one often asks
| • | Are there items defined in the program that are not used and if so what are they and where are they. |
| • | Given an item in what files is it defined, declared and used in. |
To resolve these questions a program called Refreader is included in the GAMSIDE.
