Chapter 6 Compiling and Running HP FORTRAN 77/iX Programs
Before a FORTRAN 77 program can be executed, the following must occur:
1. The FORTRAN 77 compiler translates the source code into an object
file.
2. The HP Link Editor/iX (LINKEDIT.PUB.SYS) links one or more object
files into a program file.
3. The MPE/iX operating system loads and executes the program file.
You can advance through each of these steps independently, controlling
each process along the way. In particular, you can use the MPE/iX
commands FTNXL, LINK, and RUN for steps 1, 2, and 3, respectively.
Alternatively, you can combine steps with a single MPE/iX command. The
MPE/iX command FTNXLLK performs steps 1 and 2 and the command FTNXLGO
performs steps 1, 2, and 3.
This chapter discusses the MPE/iX commands FTNXL, FTNXLLK, and FTNXLGO in
detail and also explains how you can invoke the FORTRAN 77 compiler with
the RUN command. Refer to the HP Link Editor/iX Reference Manual for
details on the LINK command.
