Hello everyone,

I am aware of $ sign, but in my knowledge it is used for conditional definitions of variables, equations, parameters and etc. What I want to do is that controlling a code block(solve statement in this case) as it can be basically done in every coding language. Here is an example:

if(x=1){
option mip=cplex;
option optcr = 0.00001;
model model1 /a,b,c/;
solve model1 min z using mip;
}else{
option mip=cplex;
option optcr = 0.00001;
model model2 /a,d,e/;
solve model2 min z using mip;
}

Is it possile to do this ?

Thanks in advance
