-
-@cmd{MATRIX DATA} command reads square matrices in one of several textual
-formats.  @cmd{MATRIX DATA} clears the dictionary and replaces it and
-reads a
-data file.
-
-Use VARIABLES to specify the variables that form the rows and columns of
-the matrices.  You may not specify a variable named @code{VARNAME_}.  You
-should specify VARIABLES first.
-
-Specify the file to read on FILE, either as a file name string or a file
-handle (@pxref{File Handles}).  If FILE is not specified then matrix data
-must immediately follow @cmd{MATRIX DATA} with a @cmd{BEGIN
-DATA}@dots{}@cmd{END DATA}
-construct (@pxref{BEGIN DATA}).
-
-The FORMAT subcommand specifies how the matrices are formatted.  LIST,
-the default, indicates that there is one line per row of matrix data;
-FREE allows single matrix rows to be broken across multiple lines.  This
-is analogous to the difference between @cmd{DATA LIST FREE} and
-@cmd{DATA LIST LIST}
-(@pxref{DATA LIST}).  LOWER, the default, indicates that the lower
-triangle of the matrix is given; UPPER indicates the upper triangle; and
-FULL indicates that the entire matrix is given.  DIAGONAL, the default,
-indicates that the diagonal is part of the data; NODIAGONAL indicates
-that it is omitted.  DIAGONAL/NODIAGONAL have no effect when FULL is
-specified.
-
-The SPLIT subcommand is used to specify @cmd{SPLIT FILE} variables for the
-input matrices (@pxref{SPLIT FILE}).  Specify either a single variable
-not specified on VARIABLES, or one or more variables that are specified
-on VARIABLES.  In the former case, the SPLIT values are not present in
-the data and ROWTYPE_ may not be specified on VARIABLES.  In the latter
-case, the SPLIT values are present in the data.
-
-Specify a list of factor variables on FACTORS.  Factor variables must
-also be listed on VARIABLES.  Factor variables are used when there are
-some variables where, for each possible combination of their values,
-statistics on the matrix variables are included in the data.
-
-If FACTORS is specified and ROWTYPE_ is not specified on VARIABLES, the
-CELLS subcommand is required.  Specify the number of factor variable
-combinations that are given.  For instance, if factor variable A has 2
-values and factor variable B has 3 values, specify 6.
-
-The N subcommand specifies a population number of observations.  When N
-is specified, one N record is output for each @cmd{SPLIT FILE}.
-
-Use CONTENTS to specify what sort of information the matrices include.
-Each possible option is described in more detail below.  When ROWTYPE_
-is specified on VARIABLES, CONTENTS is optional; otherwise, if CONTENTS
-is not specified then /CONTENTS=CORR is assumed.

-
-The exact semantics of the matrices read by @cmd{MATRIX DATA} are complex.
-Right now @cmd{MATRIX DATA} isn't too useful due to a lack of procedures
-accepting or producing related data, so these semantics aren't
-documented.  Later, they'll be described here in detail.
