Text Strings
When you are editing text, dimension values appear as follows:
@D (if displayed as a numerical value).
@S (if displayed as a symbolic value).
@O (if the dimension does not have a value, @O locates the text origin).
Special characters appear between the control characters ^A and ^B.
When you edit a note, the system preserves all of the attributes (font, height, width, or slant angle) applied to a portion of the text. However, the note appears much different from how it does on the drawing. The system breaks up a text string into portions wherever there is a new line of text or a parameter (such as dimensions), and encloses each portion of the text in braces ({}), giving it an integer label. Labels identify the initial order of the text, and any attributes for that portion. When editing text, or adding more lines, you can copy the attributes of a portion of text by using the same integer label.

If you delete the special control characters when editing text, the text string changes. If you remove ^A, all special characters become their ASCII equivalent; if you remove ^B, all text that follows becomes a special character.
You can edit view-related notes, such as section, detail, and scale notes; however, be sure not to delete or otherwise alter symbols that represent the name or scale of the view. If you edit these symbols, the system ignores the change, and displays the original note:
&view_name—name of the view
&view_scale—name of a general scaled view
&det_scale—scale of a detailed view
If you set the view_note option in the Detail option file to std_din, you can create a view-related note with the words SECTION, DETAIL, and SEE_DETAIL omitted. This only affects the creation of view-related notes. If you switch from std_ansi to std_din, the system does not update view notes.
