SET allows the user to adjust several parameters relating to PSPP’s execution. Since there are many subcommands to this command, its subcommands will be examined in groups.

For subcommands that take boolean values, ON and YES are synonymous, as are OFF and NO, when used as subcommand values.

The data input subcommands affect the way that data is read from data files. The data input subcommands are

BLANKS

This is the value assigned to an item data item that is empty or contains only white space. An argument of SYSMIS or ’.’ will cause the system-missing value to be assigned to null items. This is the default. Any real value may be assigned.

DECIMAL

This value may be set to DOT or COMMA. Setting it to DOT causes the decimal point character to be ‘.’ and the grouping character to be ‘,’. Setting it to COMMA causes the decimal point character to be ‘,’ and the grouping character to be ‘.’. The default value is determined from the system locale.

FORMAT

Allows the default numeric input/output format to be specified. The default is F8.2. See Input and Output Formats.

EPOCH

Specifies the range of years used when a 2-digit year is read from a data file or used in a date construction expression (see Date Construction). If a 4-digit year is specified for the epoch, then 2-digit years are interpreted starting from that year, known as the epoch. If AUTOMATIC (the default) is specified, then the epoch begins 69 years before the current date.

RIB

PSPP extension to set the byte ordering (endianness) used for reading data in IB or PIB format (see Binary and Hexadecimal Numeric Formats). In MSBFIRST ordering, the most-significant byte appears at the left end of a IB or PIB field. In LSBFIRST ordering, the least-significant byte appears at the left end. VAX ordering is like MSBFIRST, except that each pair of bytes is in reverse order. NATIVE, the default, is equivalent to MSBFIRST or LSBFIRST depending on the native format of the machine running PSPP.

RRB

PSPP extension to set the floating-point format used for reading data in RB format (see Binary and Hexadecimal Numeric Formats). The possibilities are:

NATIVE

The native format of the machine running PSPP. Equivalent to either IDL or IDB.

ISL

32-bit IEEE 754 single-precision floating point, in little-endian byte order.

ISB

32-bit IEEE 754 single-precision floating point, in big-endian byte order.

IDL

64-bit IEEE 754 double-precision floating point, in little-endian byte order.

IDB

64-bit IEEE 754 double-precision floating point, in big-endian byte order.

VF

32-bit VAX F format, in VAX-endian byte order.

VD

64-bit VAX D format, in VAX-endian byte order.

VG

64-bit VAX G format, in VAX-endian byte order.

ZS

32-bit IBM Z architecture short format hexadecimal floating point, in big-endian byte order.

ZL

64-bit IBM Z architecture long format hexadecimal floating point, in big-endian byte order.

Z architecture also supports IEEE 754 floating point. The ZS and ZL formats are only for use with very old input files.

The default is NATIVE.

Interaction subcommands affect the way that PSPP interacts with an online user. The interaction subcommands are

MXERRS

The maximum number of errors before PSPP halts processing of the current command file. The default is 50.

MXWARNS

The maximum number of warnings + errors before PSPP halts processing the current command file. The special value of zero means that all warning situations should be ignored. No warnings will be issued, except a single initial warning advising the user that warnings will not be given. The default value is 100.

Syntax execution subcommands control the way that PSPP commands execute. The syntax execution subcommands are

LOCALE

Overrides the system locale for the purpose of reading and writing syntax and data files. The argument should be a locale name in the general form language_country.encoding, where language and country are 2-character language and country abbreviations, respectively, and encoding is an IANA character set name. Example locales are en_US.UTF-8 (UTF-8 encoded English as spoken in the United States) and ja_JP.EUC-JP (EUC-JP encoded Japanese as spoken in Japan).

MEXPAND
MITERATE
MNEST
MPRINT

Currently not used.

MXLOOPS

The maximum number of iterations for an uncontrolled loop (see LOOP). The default max_loops is 40.

SEED

The initial pseudo-random number seed. Set to a real number or to RANDOM, which will obtain an initial seed from the current time of day.

UNDEFINED

Currently not used.

WORKSPACE

The maximum amount of memory (in kilobytes) that PSPP will use to store data being processed. If memory in excess of the workspace size is required, then PSPP will start to use temporary files to store the data. Setting a higher value will, in general, mean procedures will run faster, but may cause other applications to run slower. On platforms without virtual memory management, setting a very large workspace may cause PSPP to abort.

Data output subcommands affect the format of output data. These subcommands are

CCA
CCB
CCC
CCD
CCE

Set up custom currency formats. See Custom Currency Formats, for details.

DECIMAL

The default DOT setting causes the decimal point character to be ‘.’. A setting of COMMA causes the decimal point character to be ‘,’.

FORMAT

Allows the default numeric input/output format to be specified. The default is F8.2. See Input and Output Formats.

WIB

PSPP extension to set the byte ordering (endianness) used for writing data in IB or PIB format (see Binary and Hexadecimal Numeric Formats). In MSBFIRST ordering, the most-significant byte appears at the left end of a IB or PIB field. In LSBFIRST ordering, the least-significant byte appears at the left end. VAX ordering is like MSBFIRST, except that each pair of bytes is in reverse order. NATIVE, the default, is equivalent to MSBFIRST or LSBFIRST depending on the native format of the machine running PSPP.

WRB

PSPP extension to set the floating-point format used for writing data in RB format (see Binary and Hexadecimal Numeric Formats). The choices are the same as SET RIB. The default is NATIVE.

In the PSPP text-based interface, the output routing subcommands affect where output is sent. The following values are allowed for each of these subcommands:

OFF
NONE

Discard this kind of output.

TERMINAL

Write this output to the terminal, but not to listing files and other output devices.

LISTING

Write this output to listing files and other output devices, but not to the terminal.

ON
BOTH

Write this type of output to all output devices.

These output routing subcommands are:

ERRORS

Applies to error and warning messages. The default is BOTH.

MESSAGES

Applies to notes. The default is BOTH.

PRINTBACK

Determines whether the syntax used for input is printed back as part of the output. The default is NONE.

RESULTS

Applies to everything not in one of the above categories, such as the results of statistical procedures. The default is BOTH.

These subcommands have no effect on output in the PSPP GUI environment.

Output driver option subcommands affect output drivers’ settings. These subcommands are

HEADERS
LENGTH
MORE
WIDTH
TNUMBERS

The TNUMBERS option sets the way in which values are displayed in output tables. The valid settings are VALUES, LABELS and BOTH. If TNUMBERS is set to VALUES, then all values are displayed with their literal value (which for a numeric value is a number and for a string value an alphanumeric string). If TNUMBERS is set to LABELS, then values are displayed using their assigned labels if any. (See VALUE LABELS.) If the a value has no label, then it will be displayed using its literal value. If TNUMBERS is set to BOTH, then values will be displayed with both their label (if any) and their literal value in parentheses.

TVARS

The TVARS option sets the way in which variables are displayed in output tables. The valid settings are NAMES, LABELS and BOTH. If TVARS is set to NAMES, then all variables are displayed using their names. If TVARS is set to LABELS, then variables are displayed using their label if one has been set. If no label has been set, then the name will be used. (See VARIABLE LABELS.) If TVARS is set to BOTH, then variables will be displayed with both their label (if any) and their name in parentheses.

Logging subcommands affect logging of commands executed to external files. These subcommands are

JOURNAL
LOG

These subcommands, which are synonyms, control the journal. The default is ON, which causes commands entered interactively to be written to the journal file. Commands included from syntax files that are included interactively and error messages printed by PSPP are also written to the journal file, prefixed by ‘>’. OFF disables use of the journal.

The journal is named pspp.jnl by default. A different name may be specified.

System file subcommands affect the default format of system files produced by PSPP. These subcommands are

COMPRESSION

Not currently used.

SCOMPRESSION

Whether system files created by SAVE or XSAVE are compressed by default. The default is ON.

Security subcommands affect the operations that commands are allowed to perform. The security subcommands are

SAFER

Setting this option disables the following operations:

Be aware that this setting does not guarantee safety (commands can still overwrite files, for instance) but it is an improvement. When set, this setting cannot be reset during the same session, for obvious security reasons.

LOCALE

This item is used to set the default character encoding. The encoding may be specified either as an encoding name or alias (see http://www.iana.org/assignments/character-sets), or as a locale name. If given as a locale name, only the character encoding of the locale is relevant.

System files written by PSPP will use this encoding. System files read by PSPP, for which the encoding is unknown, will be interpreted using this encoding.

The full list of valid encodings and locale names/alias are operating system dependent. The following are all examples of acceptable syntax on common GNU/Linux systems.

SET LOCALE='iso-8859-1'.

SET LOCALE='ru_RU.cp1251'.

SET LOCALE='japanese'.

Contrary to the intuition, this command does not affect any aspect of the system’s locale.
