STRING
Type:  Pseudoverb
Use:   To create one or more new adverbs as character string
       arrays and to specify their dimensions.  May be used
       only when typing a procedure.
Grammar:  STRING*n  name1 (dim11, ...), name2 (dim21, ...), ...
       where the namei are the new string array names, the
       n is the length of each element of the arrays in
       characters, and the array dimensions, which are
       optional, are given by the dimij.  The dimij may be
       given as a single number, e.g. n, or a range, e.g.
       n TO m.  The actual length of each string element
       will not be n, but the next higher integer multiple
       of 4.
Examples:  STRING*8  JUNK1(5), JUNK2(-7 TO -3, 4)
           STRING*2 CRAZY(19, -1000 TO -987, 5)
       When the arrays are used by POPS, the subscripts are
       always tested to see that they are within range.  The
       data are stored in the canonical Fortran order (i.e.
       the first subscript varies fastest).  Two arrays may
       be equated if the RHS has the same or smaller total
       dimension as the LHS and the length of each element of
       the RHS is less than or equal to the length of each
       element of the LHS.  For example, JUNK2 = JUNK1 from
       above would set JUNK2(-7,1) through JUNK2(-3,1) to
       the 5 values in JUNK1 and blank fill the rest of JUNK2.
