"Point" to compiler to your source...
I don't use the Broland compiler. But, sombody here can tell you how to invoke it. I wouldn't say you have to "open" the file in the compiler, I'd say you have to "point" the compiler to your source file.
If you're using an editor that comes with a compiler (Or IDE = Integrated Development Environment) you usually have to save the source file first. So, it doesn't have to be "open" to compile.
The last time I tried-out the free Borland compiler, you had to compile from the DOS command line. Something like "bc MyFile.c"
The documentation with the compiler, or the Broland web site should tell you how to compile. If you can't figure- it out. Sombody here can help!

Code:
int main()
{
return 0;
}
