##### Commenting Command Sequences

In a macro, a non-executable comment begins with an exclamation point (!). You can place a comment on its own line, or insert it after a string.

The following example demonstrates both acceptable and unacceptable forms of commenting:

    ! This is a comment
    startmacro
      ! Yet another comment
      res a 2     ! This is also a comment

      res b "     ! This is not a comment"
      res c "str" ! But, this is a comment

      !!! This is a comment, too.
    endmacro
