Unique element list

Top Previous Next

The next output item is the "Unique Element List" which contains a list of all set element known to the GAMS program in the order and capitalization style in which they will appear in the output. All unique elements are first listed in the entry order (as discussed in the Rules for Item Capitalization and Ordering chapter) and then in sorted order.

The lists for the shortmodel.gms example are:

Unique Elements in Entry Order

1 makechair maketable makelamp plantcap salecontrct

Unique Elements in Sorted Order

1 makechair makelamp maketable plantcap salecontrct

Notes:

•	The unique element list does not appear unless requested. If desired, it needs to be requested by using the command $Onuellist. $Offuellist removes the unique element listing from LST file.

•	The capitalization and order of the UELs in the list and in all GAMS output is controlled by the rules explained in the Rules for Item Capitalization and Ordering chapter.

•	The UEL list is probably only useful to check capitalization and ordering in an effort to improve output appearance and make sure nothing is omitted.
