Section 13,15: DATA

 Assigns values to variables at compile time.  The values within the
 backslashes are assigned to the preceding variables left to right;
 the number of values must equal the number of variable elements.
 Statement format:

    DATA nlist/clist/[[,] nlist/clist]...

    nlist  Is a list combining any combination of variable names,
           array names, array element names, character substring 
           names, and implied-DO lists.  (RECORDs are not allowed 
           in this list.)  Elements in the list must be separated 
           by commas.

           Subscript expressions and expressions in substring 
           references must be integer expressions containing 
           integer constants and implied-DO variables.
  
           An implied-DO list in a DATA statement takes the 
           following form:

           (dlist, i = n1,n2[,n3])

           dlist     Is a list of one or more array element 
                     names, character substring names, or 
                     implied-DO lists, separated by commas.

           i         Is the name of an integer variable.

           n1,n2,n3  Are integer constant expressions.  The 
                     expression can contain implied-DO variables 
                     of other implied-DO lists that have this 
                     implied-DO list within their ranges.

    clist  Is a list of constants separated by commas; "clist"
           constants take one of the following forms:

           c OR n *c
  
           c  Is a constant or the symbolic name of a constant.

           n  Defines the number of times the same value is to 
              be assigned to successive entities in the associated 
              "nlist"; "n" is a nonzero, unsigned integer constant 
              or the symbolic name of an unsigned integer constant.

 The DATA statement assigns the constant values in each "clist" to
 the entities in the preceding "nlist", from left to right, as they
 appear in the "nlist".  The number of constants must equal the
 number of entities in the "nlist".

 When an unsubscripted array name appears in a DATA statement,
 values are assigned to every element of that array in the order of
 subscript progression.  The associated constant list must contain
 enough values to fill the array.

 For more information on the relationship between "nlist" and
 "clist", see your DEC Fortran user manual.
