I am trying to introduce a 'pathname' into an plot output.
I have tried a few variations but with absolutely no success.

   pd 'reset'
   pd 10+?100#100
   pd 'show'
   pathname=:'/home/david/Desktop/'
   NB. pd 'save bmp "/home/david/Desktop/test1.bmp" 800 600' NB. WORKS
FINE
   pd 'save bmp "pathname,'test2.bmp' " 800 600'
|spelling error
|      pd 'save bmp "pathname,'test2.bmp' " 800 600'
|    
Could somebody clarify how can I solve the pathname problem?

Thank you;

David
