9 Program Compilation
You run the FORTRAN compiler, which resides in a file named
$SYSTEM.SYSTEM.FORTRAN, by using the TACL implied RUN command.
The FORTRAN compiler accepts source files containing FORTRAN statements,
comment lines, and compiler directives. Source files alone or in combination with other
source files and object files constitute the input to a compilation. Topics covered in this
section include:
The compilation of a FORTRAN program involves the following three processes:
•
FORTRAN, which compiles code and calls BINSERV and SYMSERV for additional
processing as needed. FORTRAN produces all listings after BINSERV and
SYMSERV have completed processing.
•
BINSERV, the compile-time binder, is present throughout a compilation (unless you
specify only syntax checking). BINSERV stops when it detects an error in the
source code. Output listings always contain binder statistics if an object file was
produced.
•
SYMSERV, which produces object-file symbol tables and source level cross-
reference information. SYMSERV is present throughout a compilation.
FORTRAN starts BINSERV and SYMSERV automatically. Figure 9-1 shows the
relationship among the processes.
