The .tw suffix controls field width when putting the text associated with identifiers. When specified it overrides the option put_string_width.


The value of the .tw suffix is an integer in the range {0..``option listing_page_width``} and the default is -1.


  • The suffix .tw is initialized to -1. When its value is not equal to -1 AIMMS considers it specified.

  • The suffix .tw is a legacy from GAMS and AIMMS 2.
