12.6.8 EDIT$ Function
  The EDIT$ function performs one or more string editing
  functions, depending on the value of an argument you sup-
  ply. The input string remains unchanged. In the following
  example, stu_rec is a string expression and 32 determines the
  editing function performed:
  EDIT$(stu_rec,32)

  Table 12-2 shows the action BASIC takes for a given value of
  the integer expression.

  All values are additive; for example, by specifying 168, you
  can perform the following:

  .
        Discard leading spaces and tabs (value 8)
  .
        Convert lowercase letters to uppercase (value 32)
  .
        Discard trailing spaces and tabs (value 128)

  The following example requests an input string, discards all
  spaces and tabs, converts lowercase letters to uppercase, and
  converts brackets to parentheses:
  LINPUT "PLEASE TYPE A STRING";input_string$
  new_string$ = EDIT$(input_string$, 2% + 32% + 64%)
  PRINT new_string$
  END

  Output
  PLEASE TYPE A STRING? 88 abc

                                                    [5,5]
  88ABC(5,5)
