When <em>allbranch</em> is on, the operator 
<A HREF=r37_0179.html>solve</A> selects all 
branches of solutions. 
When <em>allbranch</em> is off, it selects only the principal 
branches. Default is <em>on</em>.

<A HREF=r37_0138.html>arbint</A>(1) indicates an arbitrary integer, which is giv
en a 
unique identifier by REDUCE, showing that there are infinitely many 
solutions of this type. When <em>allbranch</em> is off, the single 
canonical solution is given.
