PASCALPREP
Compiles and prepares a compatibility mode Pascal/V program. Pascal/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 PASXLLK.
Syntax
PASCALPREP [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 PASTEXT.
Default is $STDIN. $STDIN is the current input
device, usually your terminal.
PASTEXT cannot be backreferenced as an actual file
designator in the command parameter list. For
further information, refer to the "Implicit FILE
Commands for Subsystems" discussion of the FILE
command.
progfile Actual file designator of the program file to which
the prepared program segments are written. When
progfile is omitted, 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 PASLIST.
Default is $STDLIST. $STDLIST is usually your
terminal if you are running Pascal/V interactively,
or the printer if you are running a batch job.
PASLIST cannot be backreferenced as an actual file
designator 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 Pascal
programming language to pass initial compiler
options to a program. Pascal/V brackets the
quotedstring with dollar signs and places it before
the first line of source code in the text file.
Operation Notes
The PASCALPREP command compiles and prepares a compatibility mode
Pascal/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 PASLIST (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 MPE 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 a Pascal/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.
PASCALPREP
To compile and prepare a Pascal/V source program from the source file
PASCSRC, store it in PASCPROG, and send the listing to your standard list
device, enter:
