This parameter causes the Tracer to automatically skip lines that contain no executable statement, with the exception of the first line in the function, and in the case of a traditional function (not a dfn), the last line if it is a comment. SkipLines is an integer made up of the sum of the following values:

1 Skip blank lines. See also Skip blank lines when tracing.
2 Skip comment lines. See also Skip comment lines when tracing.
4 Skip locals lines. See also Skip locals lines when tracing.
