/sys$common/syshlp/helplib.hlb FORTRAN, Data, Scalar Reference  *Conan The Librarian (sorry for the slow response - running on an old VAX)

  A scalar reference is a scalar variable, scalar record field, array
  element, constant, character substring, or expression that resolves
  into a single, typed data item.  For example:

  Data Declarations:

     INTEGER INT, INTARY (10)
       . . .
     STRUCTURE /STRA/
         INTEGER  INTFLD, INTFLDARY (10)
     END STRUCTURE
       . . .
     STRUCTURE /STRB/
         CHARACTER*20  CHARFLD
         INTEGER  INTFLD, INTFLDARY (10)
         STRUCTURE STRUCFLD
             COMPLEX  CPXFLD, CPXFLDARY (10)
         END STRUCTURE
         RECORD  /STRA/  RECFLD, RECFLDARY (10)
     END STRUCTURE
       . . .
     RECORD  /STRB/  REC, RECARY (10)

  Reference Examples:

     INT --- Is a numeric variable.

     INTARY(1)  --- Is a numeric array element.

     REC.INTFLD --- Is a numeric field.

     REC.INTFLDARY(1) --- Is a numeric element of an array field.

     CHARVAR(5:10) --- Is a substring expression of a character
                       variable.

     REC.CHARFLD(5:10) --- Is a substring expression of a character
                           field.

  Note:  A scalar memory reference is the same as a scalar reference,
  excluding constants and expressions.
