He, he... very good question to be included in FAQ list.
See, when you use ANSI strings, you need to put double \,
i.e. to do "main\\poo". But $() macro constructor is implemented
using stringfication operator '#' which performs this task
automatically, so you need to put SymFind($(main\poo)), and it
will expand into a correct sequence. When you use $(main\\poo)
it become main\\\poo, so '\p' is an invalid sequence. This is
not a bug, this is a feature of '#' operator. Anyway, it need
to be quoted in the documentation.
