Comment lines are used to add documentation to a CSL model file by denoting lines of text which should be ignored by the translator.  Any text following the exclamation mark (!) on a line of code indicates that the text following the mark should be treated as a comment.



     ! This is a comment




The line continuation marker ("..." ellipsis) is used at the end of a line of code to indicate that the current statement is continued on the following line.  This is convenient for long equations which cannot be easily written on a single line of code.
