Comments

 Comments document the actions or elements  of  a  program.   The
 text  of  a  comment  can  contain  any ASCII character except a
 nonprinting control character, such as an ESCAPE character.  You
 can  place  comments  anywhere in a program that white space can
 appear.

 You signify a comment with braces  or  with  a  parenthesis  and
 asterisk pair, as follows:

 Example:

    { This is a comment }
    (* This is also a comment *) 

 VSI Pascal allows you  to  mix  the  two  symbol  pairs  in  one
 comment, as follows:

    { The delimiters of this comment do not match. *)
    (* VSI Pascal allows you to mix delimiters in this way. }

 VSI Pascal does not allow you to nest comments.   The  following
 example  causes a compile-time error because the comment ends at
 the first closing delimiter (}).

 Example
    The following is illegal:
    (* Comments can not be nested { in VSI Pascal } within
        a program *)
