TABSET Request
Format:
n1
TABSET
TABS
is the column in the record at which the line is
to begin.
n2 ••• nN are column positions for logical tab settings. If
omitted, the default tab settings are used.
Usage:
This request enables the user to establish his own internal
or logical tab settings for a record,. The tab settings
determine the number of spaces to be inserted in the line
when either the 10gical tab character or the tab key is
used.
The TAB SET request is followed by from one to eleven numbers
that do not exceed the value of 80. The first number
indicates the column in which the record begins" and the
following ten numbers specify the logical tab settings.
If more than eleven numbers are specified, only the first
eleven are used.. Input lines are truncated to 71 or 12
characters, when tabbing indicates a column position above
71. and when serialization is in effect. Otherwise input
lines are truncated to 80 characters, even if a number
greater than 80 is specified.
If the first number, specifying the column in which the
record begins, is not equal to 1, all input to the file will
start at the specified column in the record and all previous
columns are set to blanks. The EDIT requests BLANK, FIND,
and OVERLAY consider each record to begin in column 1,
regardless of the first specified tab value. The EDIT
requests INSERT and RETYPE interpret the beginning column
position and process the specified line in the same manner
as input to the Input environment.
The TABSET request overrides the assumed logical tab
settings, such as for FORTRAN, PLI, and SYSIN filetypes.
The user-defined tab settings apply on1y to the file during
the current EDIT command. If EDIT is issued again for the
same file,• the assumed logical tab settings are in effect
until TABSET is reissued.
If TAB SET is issued without specifying any values, the
logical tab settings are reset to the default settings for
the filetype of the file being edited,.
