PASCAL



PASCAL

     Compiles 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 PASXL. (CM)

SYNTAX


PASCAL [textfile][,[uslfile][,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.

uslfile Actual file designator of the USL file to which the
object code is stored. This can be any binary output
file with a file code of USL or 1024. Its formal
file designator is PASUSL. If the uslfile parameter
is omitted, the object code is saved to the
temporary file $OLDPASS. If entered, this
parameter indicates that the USL file was created in
one of four ways

o By using the MPE/iX SAVE command to save the
default USL file $OLDPASS, created during a
previous compilation.

o By building the USL with the MPE V/E Segmenter -
BUILDUSL command. Refer to the MPE Segmenter
Reference Manual (30000-90011).

o By creating a new USL file and specifying the
MPE/iX BUILD command with a file code of USL or 1024.

o By specifying a nonexistent uslfile parameter,
thereby creating a permanent file of the correct
size and type.

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.

NOTE


The formal file designators used in this command (PASTEXT, PASUSL, and
PASLIST) 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 Pascal/V 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

     The PASCAL command compiles a Compatibility Mode Pascal/V program
and stores the object code in a User Subprogram Library (USL)
file on disk. If textfile is not specified, MPE/iX expects the
source program to be entered from your standard input device. If
you do not specify a listfile, MPE/iX sends the program listing to
your standard list device and identifies it by the formal file
designator, PASLIST.

If you create the USL prior to compilation, you must specify
a file code of USL or 1024. If you omit the uslfile
parameter, the object code is saved in the temporary file
domain as $OLDPASS. To keep it as a permanent file, you
must save $OLDPASS under another 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.

EXAMPLE(S)

     The following example compiles a Pascal/V program entered from
the standard input device and stores the object code in the
USL file $OLDPASS. The listing is then sent to the standard
list device.

PASCAL

The next example compiles a Pascal/V program contained in the
disk file PASCSRC, and stores the object code in the USL
file PASCOBJ. The program listing is stored in the disk
file LISTFILE.
