                              boolean editable)

  For initalizing the source code when opening an ASM file

  Specified by:
    `setSourceCode` in interface `MARSTextEditingArea`
  Parameters:
    `s` - String containing text
    `editable` - set true if code is editable else false

### discardAllUndoableEdits

    public void discardAllUndoableEdits()

  Finds next occurrence of text in a forward search of a string. Search begins at the current cursor location, and wraps around when the end of the string is reached.

  Specified by:
    `doFindText` in interface `MARSTextEditingArea`
  Parameters:
    `find` - the text to locate in the string
    `caseSensitive` - true if search is to be case-sensitive, false otherwise

  Parameters:
    `input` - the string to search
    `find` - the string to find

    `replace` - the text to replace the find text with - if the find text exists
    `caseSensitive` - true for case sensitive. false to ignore case
  Returns:
    Returns TEXT_FOUND if not initially at end of selected match and matching occurrence is found. Returns TEXT_NOT_FOUND if the text is not matched. Returns TEXT_REPLACED_NOT_FOUND_NEXT if replacement is successful but there are no additional matches. Returns TEXT_REPLACED_FOUND_NEXT if reaplacement is successful and there is at least one additional match.

### doReplaceAll
