Here are the codes to begin Superscript on an ImageWriter:
Superscript Begin: ESCAPE l1 ESCAPE r ESCAPE T20 CONTROL J
Superscript End: ESCAPE f CONTROL J ESCAPE T24 (66 lines per page)
Superscript End: ESCAPE f CONTROL J ESCAPE T18 (72 lines per page)
An ESCAPE c should not be used in the Superscript End code string. The ESCAPE c generates a carriage return which will, depending upon the setting for carriage return line feed, force all text following the Superscript end to be printed over the first part of the same line or on a new line.
Also, when giving the codes for Superscripting, the ESCAPE T20 may be adjusted to a greater or lesser value depending on the height of the desired Superscript. For 66 lines per page, an ESCAPE T value of 20 is almost a full character above the current text line, where as, an ESCAPE T value of 12 is about 1/2 character above the current text line.
