ZA -- Place annotation on graphics frame at cursor position
  ZA color height justify <keywords> "text
Parameters:
  color | graphics color level; 0 for erase (def=1)
  height | pixel height to draw text/symbols (def=10 for text; cursor
           height for TCYC= symbol)
  justify | L=left, R=right, C=center, V=vertical, M=mouse
            N=numerous (def=L)
  "text | text to write on the graphics frame
  "$text | displays weather symbols or arrows on the graphics frame; see
           the McIDAS Users Guide for valid choices
Keywords:
  Ang= | angle to write text; do not use with the FONT command or global
         keyword, or keywords ENCL or TCYC
  Encl=C | draws a circle around the text in the N mode
      =E | draws an ellipse around the text in the N mode
  FULlframe=YES | use the entire frame for output, regardless
                  of the frame's panel configuration; do not use
                  FUL=YES with the global keyword PANEL
           =NO  | limit output to the current panel or the panel
                  specified in the global keyword PAN (def)
  Gra= | graphics frame number (def=current)
  POS=lin ele | TV line and element position to draw text, symbols or
                arrows (def=current cursor position)
  TCYc=color hemi | plots a hurricane or tropical storm symbol where
                    color - graphics color level of the symbol's center;
                            specify X to leave the center blank
                    hemi - N or S for northern or southern hemisphere;
                           determines direction of the spirals (def=S)
  Wid= | graphics line width, in pixels; the maximum is 64 (def=current)
Remarks:
  If you choose the M(ouse) option, clicking the middle mouse button
  repositions the start of the text at the cursor location. Clicking the
  right button repositions the end of the text at the cursor location.
  The height is scaled as needed. Using the FONT command or global keyword
  with the M option positions the text horizontally at various sizes. You
  can't change the angle of the text.

  If you choose the N(umerous) option, clicking the middle mouse button
  draws the text, centered at the cursor location. Clicking the right
  button erases the last drawn text.

  When ENCL= is used, the practical maximum number of characters is 3.
