void ltol3(); ltol3(cp,lp,N);
The "ltol3" function converts longs into three-byte integers. Three-byte integers let you "pack" values into a character string and thereby save some space.
Character strings and integers are ordered in different ways on different machines. Therefore programs using "ltol3" and its partner "l3tol" may be non-portable.
