─────MAP...END MAP──────────────────────────────────────────────────────────
 
     Action
 
     Delimits a group of variable declarations within a STRUCTURE
     statement.
 
     Syntax
 
     MAP
       type-declaration(s)
       .
       .
       .
     END MAP
 
     Parameter          Description
 
     type-declaration   A variable or RECORD declaration
 
     Remarks
 
     A MAP...END MAP block must appear within a UNION...END UNION
     block.
 
     MAP variables are stored in memory contiguously, in the order of
     their appearance.
 
     A UNION block must have at least two maps. The UNION block assigns
     two or more maps to the same memory location.

     Examples
 
     Within a structure, maps can contain variables of intrinsic type:
 
           UNION
              MAP
                 CHARACTER*20 string
              END MAP
              MAP
                 INTEGER*2 number(10)
              END MAP
           END UNION
 
     Or they can contain variables with types defined in previous
     STRUCTURE statements:
 
           UNION
              MAP
                 RECORD /Cartesian/ xcoord, ycoord
              END MAP
              MAP
                 RECORD /Polar/ length, angle
              END MAP
           END UNION
