Try:

=seek(m.lcCond,'BldMstr')
replace Street with m.lcNewStreetName, ;
               ccode with m.lcNewCode, ;
		town with m.lcNewTown, ModiType with 'C', ;			
		(.cWorkField) with .cReplVal ;
		while upper(ccode+town+Street=m.lcCond in BldMstr

It uses the index explicitly so you don't need to worry about Rushmore.

HTH.
