Commenting out SDL script (SDL script)
Use the Dollar character ($) to comment out a line in your SDL script.
Example
In this example, the first line is treated as a comment because of the $ character.
$ Ensure file extensions have dots
%if "." %isin %getvar "sysFileExtension" %then
%else
%setvar "sysFileExtension" = (".") & (%getvar "sysFileExtension")
%endif
