   1.$ LINE = "   THIS   LINE   CONTAINS A ""  QUOTED  "" WORD"
     $ SHOW SYMBOL LINE
       LINE =  "    THIS    LINE    CONTAINS A "  QUOTED  " WORD"
     $ NEW_LINE = F$EDIT(LINE, "COMPRESS, TRIM")
     $ SHOW SYMBOL NEW_LINE
       NEW_LINE = "THIS LINE CONTAINS A "  QUOTED  " WORD"

     This example uses the F$EDIT function to compress and trim a
     string by replacing multiple blanks with a single blank, and by
     removing leading and trailing blanks. The string LINE contains
     quotation marks around the word QUOTED. (To enter quotation
     marks into a character string, use double quotation marks in
     the assignment statement.)

     Note that the F$EDIT function does not compress the spaces in
     the quoted section of the string; therefore, the spaces are
     retained around the word QUOTED.

   2.$ LOOP:
     $      READ/END_OF_FILE = DONE INPUT_FILE RECORD
     $      RECORD = F$EDIT(RECORD, "TRIM, UPCASE")
     $      WRITE OUTPUT_FILE RECORD
     $      GOTO LOOP
        .
        .
        .

     This example sets up a loop to read records from a file, to
     edit them, and to write them to an output file. The edited
     records have leading and trailing blanks removed, and are
     converted to uppercase.

   3.$ UNCOMMENT_LINE = F$EDIT("$ DIR ! THIS IS THE COMMENT", "UNCOMMENT")
     $ SHOW SYMBOL UNCOMMENT_LINE
     $ UNCOMMENT_LINE = "$ DIR"

     This example uses the F$EDIT function to remove comments.
