MPE/iX reserves certain file designators for system defined files. System defined files are reserved words that refer to a specific type of system file.

$STDIN: refers to the device that you used to initiate your current session or job. The device is normally a terminal for a session and spoolfile for a job. Data entries in this file should not have a colon in column 1. (A colon in column 1 indicates the end-of-data). Use the :EOD command to delimit data.
$STDINX: is the same as $STDIN, except that a colon in the first column does not indicate the end of data. Thus $STDINX may contain commands as well as data. Interactive programs and subsystems often use $STDINX to reference the terminal as an input file. Use :EOD or :EOF to indicate the end of data.
$STDLIST: is the device designated as the session or job output device, the device MPE uses to respond to your commands. This device is normally a terminal for sessions and line printer for jobs.
$NULL: is a file designator that is used to tell MPE to read from or write to a non-existent file as though the input-output operation were successful. This file is usually used to discard output.
$NEWPASS: is a temporary disk file. MPE uses $NEWPASS to store information during the execution of a program. When a program closes $NEWPASS, the system automatically changes its name to $OLDPASS.
$OLDPASS: is a temporary disk file containing the contents of the last $NEWPASS file closed. When a $NEWPASS file is renamed $OLDPASS, the system deletes the previous version of $OLDPASS.

You can use $NEWPASS and $OLDPASS when compiling and preparing a program. MPE compilers write object code to $NEWPASS during compilation. When compilation is complete, the compiler closes $NEWPASS and the system renames the object code (USL) file $OLDPASS. When you prepare the USL file ($OLDPASS), the system stores prepared (executable) code in the $NEWPASS file. When preparation is complete, the system closes $NEWPASS and renames the executable code file $OLDPASS. Use the SAVE command to save the program stored in $OLDPASS to a permanent file.

Table 7-2 Carriage Control Directives

Octal Code (ASCII)	Description of Carriage Action
%2 - %37 (" ")	Single space (with or without automatic page eject)
%40 - %52 (" ")	Single space (with or without automatic page eject)
%53 ("+")	No space, return (next printing at column 1), cannot be used more than once on the HP 2608A/S without losing data
%54 (" ")	Single space (with or without automatic page eject)
%55 ("-")	Triple space (with or without automatic page eject)
%56 - %57 (" ")	Single space (with or without automatic page eject)
%60 ("0")	Double space (with or without automatic page eject)
%61 ("1 ")	Conditional page eject (form feed) performed by the software; if the printer is not at top-of-form, a page eject is performed. Ignored if: Postspace mode The current request has a transfer count of 0 and the previous request was `FOPEN`, `HPFOPEN`, `FCLOSE`, or `FWRITE` specifying a carriage-control directive of %61. Prespace mode Both the current request and the previous request have transfer counts of 0, and the current request and previous request are any combination of `FOPEN`, `HPFOPEN`, `FCLOSE`, or `FWRITE` specifying a carriage-control of %61.
%62	Skip to one line before top of form (valid for HP 2608S and 2563A printers only)
%63	A conditional page eject form feed is performed by the printer; not at top-of-form, a page eject is performed (valid for HP 2608S and 2563A printers only)
%62 - %77 (" ")	Single space (with or without automatic page eject; for terminals)
%104 - %177 (" ")	Single space (with or without automatic page eject; for terminals)
%2`nn`	Space `nn` lines (no automatic page eject); `nn` is any octal number from 0 through 77
%300 - %313	Select VFC Channel 1 - 12 (HP 2613, 2617, 2618, 2619)
%300 - %317	Select VFC Channel 1 - 16 (HP 2608A/S)
%300	Skip to top of form (page eject)
%301	Skip to bottom of form
%302	Single spacing with automatic page eject
%303	Skip to next odd line with automatic page eject
%304	Skip to next third line with automatic page eject
%305	Skip to next 1/2 page
%306	Skip to next 1/4 page
%307	Skip to next 1/6 page
%310	Skip to bottom of form
%311	User option (HP 2613/17/18/19), skip to one line before bottom of form (HP 2608A/S)
%312	User option (HP 2613/17/18/19), skip to one line before top of form (HP 2608A/S)
%313	User option (HP 2613/17/18/19), skip to top of form (HP 2608A)
%314	Skip to next seventh line with automatic page eject
%315	Skip to next sixth line with automatic page eject
%316	Skip to next fifth line with automatic page eject
%317	Skip to next fourth line with automatic page eject
%310 - %317	(HP 2607)
%314 - %317	(HP 2613/17/18/19)
%320	No space, no return (next printing physically follows this)
%321-%377 (" ")	Single space (with or without automatic page eject)
%400 or %100	Sets postspace movement option (prints first, then spaces). If previous option was prespace movement, the driver outputs a line with a skip to VFC Channel 3 (automatic page eject in effect) or a one line advance (equivalent to an octal code of %201 without automatic page eject) to clear the buffer
%401 or %101	Sets prespace movement option (spaces first, then prints)
%402 or %102	Sets single-space option, with automatic page eject (60 lines per page)
%403 or %103	Sets single-space option, without automatic page eject (66 lines per page)

NOTE: If octal codes %55 and %60 are selected with automatic page eject in effect (by default or following an octal code of %102 or %402), the resulting skip is to a location absolute to the page. A code of %60 is replaced by %303, and a code of %55 is replaced by %304. Therefore, the resulting skip can be less than two or three lines, respectively.

If automatic page eject is not in effect, a true double or triple space results, but the perforation between pages is not automatically skipped. For the HP 2608S and 2563A, if auto-eject and feature mode are in effect, a code of %60 is replaced by two codes of %302, and a code of %55 is replaced by three codes of %302. The resulting skip is double or triple space with auto-eject, respectively.
