solve and multiple solutions



The user documentation for globalsolve says:

 "When solving anything other than two or more linear equations, `solve' 
ignores `globalsolve'."

To read this documentation, enter ? globalsolve.  To loop over the members 
of the solution, you
can do something similar to:

sol : solve(b^2=1);

for sx in sol do (
    subst(sx, ....),
    ....)
