The problem is that the variables involved go out of scope when you leave the function. To do what you want it to do just change it to be macro substitution.

FUNCTION SCOPE (cDbf,cField,xStart,xEnd)
LOCAL lcFilterString
SELECT (cDbf)
DO CASE

   CASE TYPE("xStart") = "D"
      lcFilterString = "set filter to between("+cField+",{"+DTOC(xStart)+"},{"+DTOC(xEnd)+"})"
   CASE TYPE("xStart") = "C"
      lcFilterString = "set filter to between("+cField+",'"+xStart+"','"+xEnd+"')"
   CASE TYPE("xStart") = "N" OR TYPE("xStart") = "I"
      lcFilterString = "set filter to between("+cField+","+xStart+","+xEnd+")"
ENDCASE
*-- Set the filter on selected table
&lcFilterString
ENDFUNC

The call to the routine stays the same. The only requirement is that both variables to check must be of the same type. You might want to add more checking, I assumed you might want to use it for more than just filtering on date fields.
