A control line (with a '-' in the control column) in the print list
or in an include file (driver) and having the form
- shadow <shadow_character>: [pre_code] [post_code]
where [pre_code] and (optional) [post_code] are defined earlier
defines the function of the <character> of the shadow line in the PRINT
operation.
Thus when printing a character, say A, having <shadow_character> on
the shadow line, the following sequence will be printed:
[pre_code]A[post_code]
For example, the subscripts may be printed by defining '2' (which is
the standard attribute for subscripts) as a shadow character as
- shadow 2: [INDEX][half_line_down] [MAIN][half_line_up]
provided that the control words appearing in the definition are
properly specified earlier.
