Hello Andrew:

Thank you very much for your response and suggestion for the specification to 
glp_set_col. I changed that portion of the code and now I do get the correct 
solution with the 4.51 version. It is interesting that previous versions did 
not manifest the error as 4.51 did.

Thanks for your help and also for your work in GLPK.
