Rendition Controls Rendition control escape sequences tell TFORM to custom-print given
segments of text (which you enclose in parentheses). You can nest an
escape sequence within another (boldface and overstrike, for example, or
subscript and underline) to achieve different printing effects. A nested
rendition control can begin anywhere within the scope of an outer one;
each closing escape parenthesis in sequence terminates the most recent
rendition control. Finally, rendition controls can act upon text that extends
over multiple lines.
A rendition control escape sequence consists of five parts. The trigger
character is first, signaling TFORM of the escape sequence. It is followed
by one of the words BOLD, DOWN, FONT, OVERSTRIKE, SHADOW,
UNDERLINE, or UP (or a three-letter abbreviation of any but the last). A
left parenthesis follows the keyword, and the text to be custom printed
comes next. Another trigger and a closing right parenthesis ends the
rendition control escape sequence.
The following examples illustrate how you can tell TFORM to boldface,
change fonts, overstrike, shadow type, subscript, superscript, or underline
text in your file.
Boldface Type The BOLD rendition control specifies that the enclosed text is to be printed
in boldface type. It looks like this:
\BOLD ( text \)
The 5530 letter-quality printer does this by overprinting each character on
itself four times. All other supported printers overprint each character five
times. For example:
This line is printed in boldface type.
