To Link an Interactive C Program
After you edit a C program, you must compile and link it. Consider the following information for compiling a program:
On Windows—You must define two environment variables:
NT_COMPILER
—Its value must be the 32-bit incremental C compiler command.
LIB
—Its value must be the directory path from the load point of the compiler to its libraries (.LIB files)
1. Click Tools > Relations. The Relations dialog box opens.
2. Click Utilities > User Prog > Link. The system starts compiling the program. If the system detects errors, it prints error messages in the startup window. If necessary, edit and relink the program.
