My problem deals with about 10,000 integer variables. Any recommendation of 
what modification needs to be done in the lpx_integer routine to cater for 
10,000 integer variables?

If your problem is a capacitated transhipment problem,
you're in like Flynn.

If it's not and GLPK can't solve it,
look for more constraints or a better formulation.
