Compiles an HP Pascal/iX program. HP Pascal/iX is not part
of the 900 Series HP 3000 Computer System Fundamental
Operating Software and must be purchased separately. (NM)
PASXL [textfile][,[objectfile][,[listfile][,libfile]]]
[;INFO=quotedstring]
textfile The name of the text file that contains the
sourcecode to be compiled. This is an ASCII file
that you prepare with an editor such as EDIT/V. The
formal file designator is PASTEXT.
If you are running HP Pascal/iX from your terminal,
you will probably specify a disk textfile. If you
do not specify textfile, then the default file is
$STDIN. $STDIN is the current input device,
usually your terminal.
When textfile is your terminal, you can enter source
code interactively in response to the ">" prompt.
When you have entered all the source code, type a
colon () in response to the prompt to end the
interactive input.
The source code to be compiled can be a program or a
list of modules.
objectfile Actual file designator of the object file to which
the object code is stored. This file is stored in
binary form and has a file code of either NMOBJ
(1461) or NMRL (1033). Its formal file designator
is PASOBJ. If the objectfile parameter is omitted,
the object code is saved to the temporary file
$OLDPASS.
If you specify objectfile, the compiler will store
the object file in a permanent file of the correct
size and type, and with the name you specified. If
a file of the same name already exists, the object
code will overwrite that file.
If the compiler issues an error message telling you
that a new or existing object file you are trying to
compile to is too small, you will have to build the
object file with a larger size and recompile to it.
You may use the MPE/iX SAVE command to store
$OLDPASS as a permanent file under another name.
listfile The name of the file on which the compiler writes
the program listing. It can be any ASCII file. The
default is $STDLIST, which is usually the terminal,
if you are running HP Pascal/iX from a terminal; it
is usually the printer, if you are running a batch
job. The formal file designator is PASLIST.
If your terminal is both textfile and listfile, the
compiler does not write the program listing on the
terminal.
If listfile is $NULL or a file other than $STDLIST,
the compiler displays on $STDLIST those lines that
contain errors.
libfile The name of the HP Pascal/iX library file that the
compiler searches if a search path is not specified
with the compiler option SEARCH. The default is
PASLIB in your group and account.
quotedstring A parameter for the compiler. It is a quoted string
of no more than 132 characters (including the single
or double quote marks that enclose it).
The quotedstring string used in the HP Pascal/iX
programming language to pass initial compiler
options to the compiler. HP Pascal/iX
brackets the quotedstring string with dollar signs
($) and places the string before the first line of
source code in the text file.
The formal file designators used in this command (PASTEXT, PASOBJ, PASLIST, PASLIB) cannot be backreferenced as actual file designators in the command parameter list.
The PASXL command compiles an HP Pascal/iX program and
stores the object code in a permanent file (objectfile) or
in $OLDPASS if you do not specify an object file. If
textfile is omitted, the compiler expects the source
program to be entered from your standard input device. If
you do not specify listfile, the compiler sends the program
listing to by the
formal file designator PASLIST. The default is $STDIN.
This command is implemented as a command file. If you set the HPPATH
variable to null (SETVAR HP PATH ""), the command file will not be
executed, and the command will fail.
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 an HP Pascal/iX program
entered from your standard input device and stores the
object program in the object file $OLDPASS. The listing is
then sent to your standard list device.
PASXL
The next example compiles an HP Pascal/iX program contained
in the disk file SOURCE, and stores the object program in
the object file OBJECT. The program listing is stored in
the disk file LISTFILE.
PASXL SOURCE,OBJECT,LISTFILE
Program development in the Native Mode of MPE/iX uses the
new LINK command in place of the MPE V/E PREP command.
This produces a significant change in the method of linking
code that you must take into account.
If you have created a program called MAIN and a subprogram
called SUB, each contained in a separate file, you might
choose to handle it this way in MPE V/E
PASCAL MAIN, SOMEUSL
PASCAL SUB, SOMEUSL
PREP SOMEUSL, SOMEPROG
RUN SOMEPROG
The second command appends the code from SUB to SOMEUSL.
However, LINK (in MPE/iX Native Mode) does not append SUB.
In MPE/iX, you must compile the source files into separate
object files and then use the LinkEditor to link the two
object files into the program file, as in this example
PASXL MAIN, OBJMAIN
PASXL SUB, OBJSUB
LINK from=objmain,objsub;to=someprog
RUN SOMEPROG
However, if an NMRL is used instead of an NMOBJ, the above can be
simplified to the following:
BUILD RLFILE;DISC=10000;CODE=NMRL
PASXL MAIN, RLFILE
PASXL SUB, RLFILE
LINK RLFILE, SOMEPROG
RUN SOMEPROG
Commands: PASXLGO, PASXLLK, LINK
