Creates a record structure consisting of the variables and arrays
  specified in a previous structure declaration.  Statement format:

     RECORD /str/rnlist[,/str/rnlist...]

     str     Is the name of a previously declared structure.

     rnlist  Is a list of one or more variable names, array
             names, or array declarators, separated by commas.
             All of the records named in this list have the
             same structure and are allocated separately in
             memory.

  Record variables can be used in COMMON and DIMENSION statements,
  but not in DATA, EQUIVALENCE, or NAMELIST statements.

  Records initially have undefined values unless you have defined
  their values in structure declarations.
