COLEX(1)                           |STAT                    August 11, 1986

NAME
     colex - column/field extraction/formatting

SYNOPSIS
     colex [-fiqtv] [-F format] column numbers

DESCRIPTION
     _▶08◀c_▶08◀o_▶08◀l_▶08◀e_▶08◀x extracts the named columns from the standard input and prints
     them with tabs between.  Column numbers begin with 1.  Ranges of
     column numbers can be abbreviated with arguments of the form #-#
     (e.g., 12-24).  Column ranges can be in reverse order (e.g., 5-1 to
     reverse the first five columns).

     Optionally, _▶08◀c_▶08◀o_▶08◀l_▶08◀e_▶08◀x will format output columns as integers, numbers with
     decimal points, or as numbers in exponential (scientific) notation,
     instead of the default of printing the columns as alphabetic fields.
     A format specification precedes the column range and is indicated by a
     single letter: a (alphabetic), e (exponential), i (integer), and n
     (numeric).  Each format can be preceded by an optional width and/or a
     precision.  The width tells how wide the field should be.  The
     precision tells how many digits after the decimal point should be
     printed for real numbers, or the maximum width for alphabetic fields.
     The general form is:
          [[width][.precision]format][column range]
     See the examples for simple cases.  C programmers will recognize the
     format as that used by the standard formatted printing functions.

OPTIONS
     -f   Force filling of missing columns with the string NA.

     -F format
          By default, columns without type specifiers are printed as
          alphabetic strings.  This option changes the default for all
          columns for which the format is not explicitly specified.

     -i   Ignore missing columns.  Otherwise, a missing column, not filled
          by the -f option, is an error.

     -q   Place quotes around the printed strings.

     -t   By default, there is a tab printed after every column.  This
          option turns off the tab printing.

     -v   Validate data types in numerical columns.  If a numerical output
          format is requested, validation will print warnings when a non-
          integer or non-number is being printed as a number (usually as
          0).  By default, no checking is done.

EXAMPLES
     colex 1 2 3 4       # columns 1 through 4
     colex 1-4           # an abbreviation of the above
     colex 4-1           # columns 4-1 in reverse order
     colex -i 100-1      # reverse the columns ignoring missing columns
     colex 10.2n1-5      # columns 1-5, 10-wide, with 2 digits after decimal place
     colex -F 10.2n 5-2  # columns 5-2 in 10.2n format
     colex 4i1 5.2n2-3 10a4# column 1 as a 4-wide integer,
                         # columns 2-3 as 5-wide numbers with 2 decimal digits,
                         # and column 4 as a 10-wide alphabetic string

LIMITS
     Use the -L option to determine the program limits.
