what i am trying to do is put the block for depth into the text box. currently I am setting it outside of the text box. was just wondering if it were possible except for creating a private character for it in editor.
you've lost me as well on this one. What "text box" is this on a vba form ? OR a VBA or Lisp routine ?
Or are you trying to paste a block into the Text editor (which it sounds like you are trying to do ) ~ the text editor is just that ... a TEXT editor , it does not support graphical entities ~ that's what the rest of Autocad is for.
If I've misunderstood then I'm afraid you'll have to explain further
User defined symbols are called blocks. Yes you can create them. If you mean user defined text symbols, yes again - you can create a new font that includes symbols (or modify a font to include new characters).
