Hello Tony, GMPL data files can be easily created with any tool that can output text files, cf. http://en.wikibooks.org/wiki/GLPK/Scripting_plus_MathProg
You could use the printf command of GMPL to create data files. When many data shall be used with the same model, I personally would use a SQL data base, which can be read with the table statement.
