The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

     Action
 
     Assigns initial values to variables.
 
     Syntax
 
     DATA nlist /clist/ [ [,] nlist /clist/]...
 
     Parameter          Description
 
     nlist              A list of variables, strings or implicit DO
                        lists to initialize. Separate list items with
                        commas.
 
     clist              A list of initial values for the items in
                        <nlist>. Values must be constants or
                        Hollerith constants, separated by commas.
 
     Remarks
 
     Structure variables may not appear in DATA statements but structure
     elements may.
 
     Variables explicitly declared as automatic may not appear in a DATA
     statement.
 
     Only local variables, arrays, and array elements can appear in a
     DATA statement.
 
     The form of an implied-DO list is as follows:
 
     (dolist, dovar = start, stop [, inc])
 
     Parameter          Description
 
     dolist             A list of array-element names and implied-DO
                        lists
 
     dovar              An integer variable
 
     start, stop,       Integer-constant expressions
     inc
 
     For example, the following are implied-DO lists:
 
          (count(i), i = 5, 15, 2)
          ((array(sub,low), low = 1, 12), sub = 1, 2)
          ((result(first,second), first = 1, max), second = 1, upper)
 
     The number of iterations and the values of <dovar> are established
     from <start>, <stop>, and <inc> the same as for a DO loop except
     that the iteration count must be positive. When an implied-DO
     list appears in a DATA statement, the list items in <dolist> are
     initialized once for each iteration of the implied-DO list.
 
     Examples
 
           INTEGER n, order, alpha, list(100)
           REAL  coef(4), eps(2), pi(5), x(5,5)
           CHARACTER*12  help
 
           DATA  n /0/, order /3/
           DATA  alpha /'A'/
           DATA  coef /1.0, 2*3.0, 1.0/, eps(1) /.00001/
 
     C     The following example initializes diagonal and below in
     C     a 5x5 matrix:
           DATA  ((x(j,i), i=1,j), j=1,5) / 15*1.0 /
           DATA  pi / 5*3.14159 /
           DATA  list / 100*0 /
           DATA  help(1:4), help(5:8), help(9:12) /3*'HELP'/
