Gdxout

 Top  Previous  Next

This dollar command is used in a sequence to unload specified items to a GDX file.  It is employed using the syntax

 

$Gdxout filename

 

where filename gives the name of the GDX file (with or without the extension GDX) and the command opens the specified GDX file for writing

and

$Gdxout

 

where the command closes the specified GDX file.

The command must be used in conjunction with the command $Unload.

Example:

(gdxtrnsport.gms)

$gdxout tran

$unload i j

$unload d

$unload f

$unload b=dem a=sup

$gdxout

Notes:

•A Gdxout command followed by the name of the GDX file to use must precede all $Unload commands and opens the file.
•A Gdxout command without following arguments must succeed the Unload command or commands and closes the file.  More than one Unload can appear in between.
