FTNPREP
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 the FTNXLLK command.
Syntax
FTNPREP [textfile],[progfile][,listfile][;INFO=quotedstring]
Parameters
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 is 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:
* By using the MPE/iX 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.
* 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.
NOTE 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 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 or two double
quotation marks 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.
Operation Notes
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.
Use
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 the RESUME command continues the execution.
Examples
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 is printed on your
standard list device.
FTNPREP
To compile and prepare an HP FORTRAN 77/V source program from the source
file FORTSRC, store it in FORTPROG, and send the listing to your standard
list device, enter:
FTNPREP FORTSRC,FORTPROG
