1.0  COMPILE COMMAND

FORTRAN command string to compile one or more source files:

        FORTRAN>COMPILE srcfile1+srcfile2+srcfile3.../switch/switch...

Multiple source files in a compilation command act as if all source files
were appended together prior to the beginning of the compilation.

Switches may come before or after any source file.  Regardless of the
position of a switch, it applies to each source file in the command line.

The word "COMPILE" is optional if the command begins with a switch or
begins with a filespec that cannot be confused with the words "EXIT,"
"HELP," "RUN," "TAKE," or "COMPILE."

The /CROSS-REFERENCE, /LNMAP, and /MACHINE-CODE switches imply /LISTING.
The /NOLISTING switch implies /NOCROSS-REFERENCE, /NOLNMAP, and
/NOMACHINE-CODE.

The default device is DSK: for all filespecs in a compilation command.

The name of the last source file is used as the default name of the
object and listing files.  If the last source file does not have a name
(e.g. TTY:), FORTRAN-OUTPUT is used as the default filename.

The default extension is .REL for the object file.  The default extension
is .LST for the listing file if /CROSS-REFERENCE was not specified and
.CRF if /CROSS-REFERENCE was specified.



2.0  TAKE COMMAND

Command to process one or more FORTRAN commands from an indirect command
file:

        FORTRAN>TAKE filespec

or to have commands from indirect command file echoed:

        FORTRAN>TAKE filespec /ECHO

Indirect command files may nest up to ten levels deep.

DSK: is used as the default device of the indirect command file, and .CMD
is used as its the default extension.



3.0  RUN COMMAND

Command to run another program in this fork:

        FORTRAN>RUN filespec

or to run a program in this fork starting at a specified offset from its
start address:

        FORTRAN>RUN filespec /OFFSET:offset

SYS: is used as the default device in the filespec, and .EXE is used as
the default extension.



4.0  HELP COMMAND

Command to list this file:

        FORTRAN>HELP



5.0  EXIT COMMAND

Command to exit FORTRA:

        FORTRAN>EXIT
