[Help-glpk] Help needed

[Victor Gutierrez]

Hi

I need to pre-process some data before an optimization problem begins.

I'm doing the following:

If I have the following array of parameters:

param values = [0 0 0 0 8 9 0 0]

I would like to have in one parameter the index k where the first element of the array "values" is different of zero, i.e. 

param index := 5     due to values[5] != 0

could you help me with this.

Thank you in advance

Victor
