     10 .SH DESCRIPTION
     11 .B zsub
     12 calculates the difference of a
     13 .I minuend
     14 and a
     15 .IR subtrahend ,
     16 and stores the result in
     17 .IR difference .
     18 That is,
     19 .I difference
     20 gets
     21 .I minuend
     22 -
     23 .IR subtrahend .
