[Bug-glpk] GLPK Model Transfer to CPLEX LP File

I found there is a bug in the GLPK when transfering MathProg model to CPLEX 
LP file. While CPLEX LP does not allow for slash "/" in the model, certain 
"/" in the MathProg model is not transfered to other symbol which causes 
CPLEX reporting error. Specifically, in my MathProg model, I have a set S 
with a variable "Name1/Name2" and constraint defined as "ST_Constraint1(i in 
S): ...". Then the transfered LP file has the constraint 
"ST_Constraint1(Name1/Name2)" causing the problem. Your help to fix it will 
be appreaciated.
