@DATE The internal date when the program started. See the Date function.

@DAY The day of the month extracted from the value in @DATE.

@FALSE The compiler replaces the value with 0.

@FM A field mark, Char(254).

@IM An item mark, Char(255).

@INROWNUM Input row counter. For use in constrains and derivations in Transformer stages.

@OUTROWNUM Output row counter (per link). For use in derivations in Transformer stages.

@LOGNAME The user login name.

@MONTH The current extracted from the value in @DATE.

@NULL The null value.

@NULL.STR The internal representation of the null value, Char(128).

@PATH The pathname of the current DataStage project.

@SCHEMA The schema name of the current DataStage project.

@SM A subvalue mark (a delimiter used in UniVerse files), Char(252).

@SYSTEM.RETURN.CODE
Status codes returned by system processes or commands.

@TIME The internal time when the program started. See the Time function.

@TM A text mark (a delimiter used in UniVerse files), Char(251).

@USERNO The user number.

@VM A value mark (a delimiter used in UniVerse files), Char(253).

@WHO The name of the current DataStage project directory.
