The $* (asterisk) directive allows a comment to be embedded directly into the program’s object code at compilation.
$* " text " $* ' text ' $* \ text \
|text||The comment text, enclosed within string delimiters.|
The $* directive directs the compiler to write the quoted text directly into the object code of the program. These comments are generally used to place copyright information or version numbers into object code before it is distributed.
To place the string "HELLO" directly into the object code of a program, the code might read:
$* " DRAGONS -- Version 1.1 " $* " Copyright 1989 N. West, NBM Inc. " EQUATE TRUE TO 1, FALSE TO 0, BEL TO CHAR(7) . . .
