+rem S-BASIC of course allows traditional BASIC-style comments
+
+comment
+  In addition to the single-line REM statement, S-BASIC
+  also supports multiline comments using COMMENT...END.
+  Note that the terminating END must be the first token on
+  a line of its own.
+end
+
+comment
+  When declaring a group of variables, S-BASIC allows
+  a semi-colon, instead of the normal comma, as a separator,
+  in which event an explanatory comment can follow the
+  semi-colon and is ignored by the compiler.

+   Finally, although statements in S-BASIC are normally terminated
+   by an end-of-line, any logical statement can be continued on to
+   the following physical line with a backslash, in which event
+   anything after the backslash is ignored and can be used for
+   a comment.
