          æModified from Z/PUG Vol. 16 by John A. McCullochå
æ	This was part of a Pascal Course, as program listing #5 of Welsh &å  
æElder, Page 101. It has been modified from the listing in Volume 16 as   å
æformatted by Gerald Hewett. Furthur changes may be made to expand the    å
ærange of amounts handled. As set up it will handle amounts to $9,999.99. å
æ	Addition of the fixed point package, or conversion of numerical   å
ædata to strings will allow this to work within a computational package.  å
