Any text between curly braces is treated as a comment. For example,
xxx {This is a comment.} yyy
is treated the same as.
xxx yyy
Comments can extend across multiple lines. For example,
xxx <> yyy{This is
a multi-line
comment.}
uuu <> vvv
is treated the same as
xxx <> yyy
uuu <> vvv
Note: If you change the model while in Path Diagram view, the comments that you entered in Syntax view will be lost.
