MAT SAVE DATA <Survo data> TO <matrix file> 
saves a Survo data file (active fields) or a part of it to a matrix
file. The specifications VARS, MASK, CASES and IND are available for selecting
variables and observations to be moved. If the first active field is a
string field it will be used as the row label. Otherwise the rows are
labelled numerically. The columns are always labelled by the
corresponding field names (abbreviated to 8 first characters).

Since in many applications the order of columns (variables) is important,
it can be changed either by specifying the variables in desired order
by VARS or by observing the fact that MAT SAVE DATA sorts the columns
in alphabetic order with respect of their activation mask symbols.
For example, MASK=AYY-XX specifies the order 1,5,6,2,3 (4 omitted)
of columns (variables).
