How is GAMSBAS used in a GAMS program?
There are three elements to the use of GAMSBAS

• Modification of the GAMS program
• • In the GAMS program you must make GAMSBAS the substiute solver by entering a line like
    option lp=gamsbas; The rest of the program is like any other GAMS model.

  
  

• Creation of the bas file
• • GAMSBAS creates the saved basis on a *.bas file where the * refers to the filename from the GAMS execution instruction. Thus if you are solving a model called trnsport you receive a file called trnsport.bas.

  
  

• Usage of the bas file
• • The user can use the *.bas file in future solves by inserting the command
    $include *.bas (with the appropriate file name)
    in a subsequent GAMS program
