The DF (or FL32) command is the driver for running the compiler and linker. You can either compile and link your projects in one step with DF, or compile them with DF and then link them with LINK. You can also use LINK to build libraries of object modules. Each of these commands provides syntax instructions at the command line if you request it with the /? or /help option.
