1 MAP
 The MAP statement defines a named area  of  statically  allocated  storage
 called  a  PSECT,  declares data fields in the record, and associates them
 with program variables.

 Example

 MAP (BUF1) STRING FILL=18, LONG A(10 TO 20) 

2 Syntax

  MAP (map-name) { [ data-type ] map-item },...

    map-item:  { num-unsubs-var-name                                 }
               { num-array-name ([int-const1 TO] int-const2,...)     }
               { str-unsubs-var-name [=int-const]                    }
               { str-array-name ([int-const1 TO] 
                 int-const2,...)[=int-const]                         }
               { FILL [ (int-const) ] [=int-const]                   }
               { FILL% [ (int-const) ]                               }
               { FILL$ [ (int-const) ] [=int-const]                  }

2 DYNAMIC
 The MAP DYNAMIC statement names the variables and  arrays  whose  size
 and  position  in  a  storage  area  can  change at run-time.  The MAP
 DYNAMIC statement is used in conjunction  with  the  REMAP  statement.
 The  REMAP  statement defines or redefines the position in the storage
 area of variables named in the MAP DYNAMIC statement.

 Example

 MAP (ABC) STRING DUMMY = 512
 MAP DYNAMIC (ABC) STRING A, B, C, LONG D, E, F

3 Syntax

     MAP DYNAMIC (map-dyn-name) { [ data-type ] map-item },...

       map-dyn-name:  { map-name         }
                      { static-str-var   }

       map-item:  { num-unsubs-var-name                             }
                  { num-array-name ([int-const1 TO] int-const2,...) }
                  { str-unsubs-var-name                             }
                  { str-array-name ([int-const1 TO] int-const2,...) }
