Dear Asma,
the CPLEX file format is not aware of sets and indices. The only way you
can indicate indices is by using concatenated variable names like a(1,2).
See glpk-4.47/doc/glpk.pdf, section CPLEX LP Format.

otherwise how to specify the data and variable with two dimensions in
an .lp file.
I look at this on the internet but there are only a simple examples.
i need for example to represent one set (set MySet:=1..5;) and an
variable (var Y{i in MySet, j in MySet: i!=j} >=0, integer;).
Could somebody help me please?
Regards
Asma
