The variable names don't agree but I suppose it's a typo in the post?

Well, what are you trying to do? If you want to increment or decrement 
$PLROBJ.xcoord, you must say $PLROBJ.xcoord+=1 or $PLROBJ.xcoord-=1. 
What happens now, the variable $PLROBJ.xcoord is incremented or 
decremented by the result of showMap, like in $PLROBJ.xcoord-=showMap(), 
and showMap probably returns nil.
