 DELIM = del

 del  Is a character expression with one of the 
      following values:

 'APOSTROPHE'  Indicates that apostrophes delimit character 
               constants. All internal apostrophes are doubled.

 'QUOTE'       Indicates that quotation marks delimit character 
               constants.  All internal quotation marks are doubled.

 'NONE'        Indicates that character constants have no 
               delimiters.  No internal apostrophes or quotation

 DELIM is only allowed for files connected for formatted data
 transfer; it is ignored during input.
