Hi Gregory,
You can simply do list-to-list assignments:
{x1,x2,x3,x4,x5}={value1,value2,value3,value4,value5}
in whatever way you want, e.g.
Table[Symbol["x"<>ToString[i]],{i,5}]=Table[i,{i,5}]
Note that this is especially useful for doing parallel calculations to
obtain values not derived from loops. E.g.
{x1,x2}={ParallelEvaluate[(*some long
calculation*),{Kernels[][[1]]}],ParallelEvaluate[(*some different long
calculation*),{Kernels[][[2]]}]}
Cheers,
Zach
