COMMENT _ _ _ _ _ _ _ _ _ _ _ _ command
Beginning with the word comment, all text until the next statement terminator (; or $) is ignored.
x := a**2 comment--a is the velocity of the particle;; 2 X := A
Note that the first semicolon ends the comment and the second one terminates the original REDUCE statement.
Multiple-line comments are often needed in interactive files. The comment command allows a normal-looking text to accompany the REDUCE statements in the file.
