GAMS: display

While playing with my old column generation example http://www.amsterdamoptimization.com/pdf/colgen.pdf I wanted to change the display of of the patterns a little bit:

----    181 PARAMETER pat  pattern usage                  p1         p15         p18         p21         p25         p26         p28         p31         p34 width1       12.000                               2.000                               1.000 width2                    1.000       3.000       2.000                   1.000       1.000 width3                                            2.000       2.000       3.000                               1.000 width4                                3.000 width5                                                                                            2.000 width6                                                        1.000       1.000                   4.000       5.000 width7                                                                                3.000 width9                    3.000 width10                                                                                           1.000       1.000 width13                                                       2.000                                           1.000 Count         4.000      27.000      49.000      61.000       1.000     222.000     479.000      61.000       3.000       +         p36         p37         p38         p39         p40         p42         p43         p44         p45 width1                                            1.000                   4.000 width2                                2.000                   1.000                                           4.000 width3        1.000       2.000       1.000       1.000                   1.000       2.000       2.000 width4                                            3.000                               1.000 width6        1.000       5.000       1.000       2.000       4.000                               1.000 width7        1.000                                                                   1.000                   1.000 width8                                1.000 width9                                                                                            1.000 width10                                                                               2.000                   1.000 width11                               2.000                   3.000       3.000                   1.000 width12                   1.000 width13       2.000 Count       191.000     101.000     103.000       1.000      79.000       1.000       1.000     347.000      20.000       +       Total width1      654.000 width2     1362.000 width3     1987.000 width4      151.000 width5      122.000 width6     1946.000 width7     1649.000 width8      103.000 width9      428.000 width10      86.000 width11     793.000 width12     101.000 width13     387.000 Count      1751.000

Now I wanted to drop the zero’s after the decimal point, so I did:

option pat:0;
display pat;

This gave as result:

----    183 PARAMETER pat  pattern usage                  p1         p15         p18         p21         p25         p26         p28         p31         p34 width1           12                                   2                        ***********1 width2                        1           3           2                       1           1 width3                                                2           2           3                                   1 width4                                    3 width5                                                                                                2 width6                                                            1           1                       4           5 width7                                                                                    3 width9                        3 width10                                                                                               1           1 width13                                                           2                                               1 Count             4          27          49          61           1         222         479          61           3       +         p36         p37         p38         p39         p40         p42         p43         p44         p45 width1                                                1                       4 width2                                    2                       1                                               4 width3            1           2           1           1                       1           2           2 width4                                                3                                   1 width6            1           5           1           2           4                                   1 width7            1                                                                       1                       1 width8                                    1 width9                                                                                                1 width10                                                                                   2                       1 width11                                   2                       3           3                       1 width12                       1 width13           2 Count           191         101         103           1          79           1           1         347          20       +       Total width1          654 width2         1362 width3         1987 width4          151 width5          122 width6         1946 width7         1649 width8          103 width9          428 width10          86 width11         793 width12         101 width13         387 Count          1751

It is not clear what the stars are doing there. May be some debugging output left in the code.
