I want to place two pictures side-by-side inside a pspicture  
envinronment:  one involves plotting a curve, for which I need to set  
a much smaller yunit.  So (trying to mimic the "cat" on pp. 148-150  
of the Latex Graphics Companion) I created two commands, one to draw  
each picture, then used an \rput to place them next to each other.
Here is the code:
				\psset{yunit=0.1 mm}
				\parametricplot{-90}{90}{t sin t}
but I get the error message
! Missing number, treated as zero.
<to be read again>
l.90 				\rput(-2.8,0){\DPic}

? l.90 				\rput(-2.8,0){\DPic}

and I can't figure out what I am doing wrong.  What does the program  
in the \rput command?
