HEIGHT allows you to change the height of text.

Enter a new text height value using the numeric keys, and
press <Enter>. Remember that the value must be greater
than 0.00005.

You can continue using the TXT ATT menu to choose other
attributes to change. If this is the last, or only,
attribute that you want to change, choose DONE from the 
TXT ATT menu.

When you choose the DONE option, the Selection Menu
appears. Choose a method of selection and if prompted,
indicate the viewport that contains the text that you
want to alter.
