[Help-glpk] Newbie was wondering how

[Liberson, Gary M]

Am a newbie to GLPK, was wondering,

how do you take a data parameter

x[i,d] := data (i in stuff, d in days:
              stuff1   d1    20
              stuff1   d2    0
              stuff1   d3    3   ) ;
              

I want to sum  and take the above data do some math and yield a data
parameter that is a continuous sum by i,d yielding the result.  I want
obviously not enter the data, I would like to caculate it on the fly?

xsum[i,d] := data (i in stuff, d in days:
              stuff1    d1    20
              stuff1    d2    20
              stuff1    d3    23  ) ;

Using sum and displaying it does seem to do as I want.  Any ideas?

Thanks in advance
