Quoted text

 Top  Previous  Next

One of the allowable types of items in a put command is quoted text.  The blue entries just below all involve instances of quoted text which are used in the example putex1.gms

 

put 'Run on ' system.date '  using source file  ' system.ifile ///;

loop(Destinaton,

  put 'Report for ' , Destinaton.tl:15

  put @40 '------------  Scenario  ------------' /;

  put @41;

  loop(scenarios,put scenarios.tl:10);

  put /;

  loop(source$sum(scenarios,

        abs(savtransport(Source,Destinaton,scenarios))),

     put 'Incoming From ' source.tl @35;

     loop(scenarios,

       put savtransport(Source,Destinaton,scenarios):10:0);

     put /;

      );

  put 'Quantity demanded ' @35

 

The resultant output file follows with the blue entries corresponding to quoted text generated by the put commands above.

 

Run on 01/05/02  using source file  C:\GAMS\GAMSPDF\PutEX1.GMS

 

Report for New York                    ------------  Scenario  ------------

                                        base      scen1     scen2     scen3

Incoming From Seattle                     50       350         0         0

Incoming From San Diego                  275       275         0       525

Quantity demanded                        325       625         0       525

 

•Quoted text may be encased in a pair of single (') or double (") quotes with each the items needing to use a matching pair.  Thus the following three lines are all exactly equivalent.

 

 put 'Run on ' system.date ' using source file ' system.ifile;

 put "Run on " system.date " using source file " system.ifile;

 put 'Run on ' system.date " using source file " system.ifile;

 

•Quoted text may be specified with a length as discussed below and a justification as discussed below using commands like

 

 put 'Marginal Cost of meeting demand ':33 @35);

 put 'Marginal Cost of meeting demand ':>33 @35);
