Putting out set elements for parameters via .Tn

GAMS allows one to put out the fully write out the name and set definition of an indexed item like a parameter, variable, or equation. This is done using the suffix .tn in a put context.

put parametername.tn(setdependency)

where the set deendency is controlled by loop statements.

Examples (putex1.gms):

Suppose one wants to put out the full identiy of items in an array.  One can do this in a transport context as follows

put / "example of .tn use" //;

loop((scenarios,Source,Destinaton)$savtransport(Source,Destinaton,scenarios),

     put savtransport.tn(Source,Destinaton,scenarios):0:0 @50

         " = "

         savtransport(Source,Destinaton,scenarios) /;

     );

This will produce

example of .tn use

savtransport('Seattle',"New York",'base')         =        50.00

savtransport('Seattle','Chicago','base')          =       300.00

savtransport("San Diego","New York",'base')       =       275.00

savtransport("San Diego",'Topeka','base')         =       275.00

savtransport('Seattle',"New York",'scen1')        =       350.00

savtransport("San Diego","New York",'scen1')      =       275.00

where note the parameter name and associated set elements are printed out for each nonzero item.
