When data associated with variables or equations are to be read or written one may use
Equ=equationname.attribute Rng=DataRange Dimensions SymbolOptions
Var=variablename.attribute Rng=DataRange Dimensions SymbolOptions
but these only work for going to the spreadsheet at the moment and one should pass such items through parameters.
Notes:
| • | When writing an attribute of a variable or equation can be addressed using the attribute names .L, .M, .Lo , .Up .Prior and .Scale |
| • | The attribute names are not case sensitive. |
| • | Today attributes of variables cannot be read from a spreadsheet and included in the GDX file. Rather one must bring the item into GAMS as a parameter and use a replacement statement. A revision is planned in the near future to allow this. |
| • | Today one can only unload a whole variable into a GDX file then save selected attributes. A revision is planned in the near future to allow this. |
