Hi, I need help from anyone who knows, this code is a test for GPS receiver compiled in ICC11 without any errors ,but when I want to run it ,it didn't run why????????

What do you mean by did not run? I got the output of the printf statements. I guess you have the conditions in the #if instead of if and so probably it just goes to the end of the main where printf's are there.
What I meant is You have the condition like #if charRead=='$' But I think it should be if(charRead=='$') Because I dont think MACRO if will be true at any point. Of course the one you have given here.
