Compiles and prepares a compatibility mode FORTRAN 66/V program. FORTRAN 66/V is not part of the HP 3000 Series 900 Computer System Fundamental Operating Software and must be purchased separately.

Syntax

FORTPREP [textfile] [,[progfile] [,[listfile] [,[masterfile] [,[newfile]]]]] [;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. The 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 resides in the temporary file domain as $OLDPASS. To 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, resulting in the creation of job/session temporary file of the correct type.

listfile

Actual file designator of the file to which the program listing is written. This can be any ASCII output file. The formal file designator is FTNLIST. Default is $STDLIST.

masterfile

Actual file designator of the master file with which textfile is merged to produce a composite source. This can be any ASCII input file. The formal file designator is FTNMAST. Default is that the master file is not read; input is read from textfile, or from $STDIN if textfile is not specified.

newfile

Actual file designator of the file resulting from the merger of textfile and masterfile. This can be any ASCII output file. The formal file designator is FTNNEW. Default is that the file is not written.

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 to pass initial compiler options to a program.

NOTE: The formal file designators used in this command (FTNTEXT, FTNLIST, FTNMAST, and FTNNEW) 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.

Operation Notes

This command compiles and prepares a compatibility mode FORTRAN 66/V program into a program file stored on disk. If you do not specify a source file, MPE/iX expects the input from your standard input device. If you do not specify listfile, MPE/iX sends the output to your standard list device.

The USL file created during compilation is a system-defined temporary file $OLDPASS, which is passed directly to the MPE segmenter. The segmenter also uses the file $OLDPASS. The prepared program segments are written to it, thus overwriting any existing temporary file of that name.

If you have no need to examine the USL file, use the default for progfile. This way, MPE/iX creates a program file for you, ensuring the best results. If, on the other hand, you want to store the USL file and the program file as separate entities, specify progfile.

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

To compile and prepare a FORTRAN 66/V program entered from your standard input device, into the standard default file $OLDPASS, with the listing printed on your standard list device, enter:

 FORTPREP

To compile and prepare a FORTRAN 66/V source program from a text file named TEXTX into a program file named PROGX, with the listing sent to the list file LISTX, enter:

 FORTPREP TEXTX,PROGX,LISTX

The FORTPREP command combines the compilation and preparation steps. The compiled program segments, stored in the file $OLDPASS, are prepared and stored in the program file PROGX. Therefore, it is equivalent to:

 FORTRAN TEXTX, LISTX
PREP $OLDPASS,PROGX
