Hi Xypron,
yes you can do that and several other things. However, I am still firmly
convinced that for me the additional command line option for glpsol to
provide an initial bound for the MILP solver would be very useful.

Hello Oscar,
I agree that this obviously is possible. However, at least for me it would
be nice to have this command line option to keep the model "clean" (I do
to pass a parameter to a model from the command line you can use a script,
which will first create a data file and then pass it to glpsol (see example
below).
As glpsol can take multiple data files if necessary this does not require
many changes.
Best regards
