@p()Blanks lines do not separate paragraphs. This is deliberate. Any number of blank lines translates to a single space. This allows you to separate parts of your Interscript document with vertical white space. It is particularly useful to add blank lines before headings. For example: On-the-fly interscript for test 3 follows.
61: @head(1,'A document') 62: We are flying to the moon today. 63: @p() 64: But not just any moon. The moon of Mars. 65: 66: @head(1,'Phobos') 67: Actually, there are two Martian moons. 68: @p() 69: @p() 70: @p() 71: 72: @p() 73: 74: @p() 75: One of them is Phobos.
You should note that @p() is idempotent, which is a fancy way of saying two or more of them in a row are the same as one. You can't add extra space between paragraphs. Not even by putting dummy blank lines in between.
