Compiles and prepares a Compatibility Mode HP FORTRAN 77/V
program. HP FORTRAN 77/V is not part of the 900 Series HP
3000 Computer System Fundamental Operating Software and must
be purchased separately. The Native Mode equivalent of this
command is FTNXLLK. (CM)
textfile Actual file designator of the input file from which
the source program is read. This can be any ASCII
input file. Formal file designator is FTNTEXT.
Default is $STDIN.
progfile Actual file designator of the program file to which
the prepared program segments are written. When you
omit progfile, the MPE Segmenter creates the program
file, which will be stored in the temporary file
domain as $OLDPASS. If you do create your own
program file, you must do so in one of two ways
o By using the MPE V/E BUILD command and specifying
a file code of 1029, or PROG, and a numextents
value of 1. This file is then used by the PREP command.
o By specifying a nonexistent file in the progfile
parameter, in which case a job/session temporary
file of the correct size and type is created.
listfile Actual file designator of the file to which the
program listing is written. This can be any ASCII
output file. Formal file designator is FTNLIST.
Default is $STDLIST.
The formal file designators used in this command (FTNTEXT and FTNLIST)
cannot be backreferenced as actual file designators in the command
parameter list. For further information, refer to the "IMPLICIT FILE
COMMANDS FOR SUBSYSTEMS" discussion of the MPE/iX FILE command.
quotedstring A sequence of characters between two single
quotation marks (apostrophes) or between two double
quotation marks. You may use the delimiter as part
of the string so long as the delimiter appears
twice. Any occurrence of two single quotation marks
in a row, or two double quotes in a row, is
considered part of the string, and, therefore, not
the terminating delimiter.
INFO=quotedstring is used in the HP FORTRAN 77/V
programming language to pass initial compiler
options to a program.
The FTNPREP command compiles and prepares a Compatibility
Mode HP FORTRAN 77/V program into a program file on disk.
If you do not specify textfile, MPE/iX expects input from
the current input device. If you do not specify listfile,
MPE/iX sends the listing output to the formal file
designator FTNLIST (default $STDLIST). The USL file
$OLDPASS, created during compilation, is a temporary file
passed directly to the MPE Segmenter. You may access it
only if you do not use the default for progfile. This is
because the Segmenter also uses $OLDPASS to store the
prepared program segments, overwriting any existing
temporary file of the same name.
This command may be issued from a session, job, or program. It may
not be used in BREAK. Pressing [Break] suspends the execution of
this command. Entering RESUME continues the execution.
The following example compiles and prepares an HP FORTRAN
77/V program entered through your standard input device and
stores the prepared program segments in the file $OLDPASS.
The listing will be printed on your standard list device.
To compile and prepare an HP FORTRAN 77/V source program
from the source file FORTSRC, storing it in FORTPROG, and
sending the listing to your standard list device, enter
