i need to build a string
containing a quote.
how can o do that?

the reason is i need a system call
and windows path names may contain blank
the system call i need is similar to

"c:\Program Files\My Programs\myprog.exe" myfile.txt

so i have to build a string 
abd then this tring is used as an argument
and there it need outer quotes also.

how can i manage?
