The Compile File command creates an object (.OBJ) file from your current source file, but does not link the .OBJ file into an executable (.EXE) file. ■ Use Compile File with single-module programs or with an individual module of a multimodule program. ■ Use Build Program to compile all the changed modules of a multimodule program. ■ Use the Go command on the Run menu to execute the program after it is built.
