This is a not uncommon situation where the package routine does not behave
as the notebook routine.
The best solution may be to supply the desired symbol names to the package
routine.
MyOptimize[parms, {z1,z2,z3}]
We assume that these appear in the parms expressions. This first method is
more general and also picks up the Context of the notebook calling the
routine (such as Help Function pages).
A second method (but much more restricted for the user) is to put the
relevant package code inside a With statement:
With[{z1=Global`z1, z2=Global`z2, z3=Global`z3},...]
A third method is to use a default argument:
MyOptimize[parms_, vars_List:{Global`z1,Global`z2,Global`z3}]

Dear List:
I made a package with a function that has a minimization. The minimization
returns, as should be, the value of the optimization, and then the values
of the variables, in the form {z1->10,z2->20,z3->50}.
In the notebook, this works perfectly well. In the package, however, the
function throws back the variables in the form
{contextname`z1->10,contextname`z2->20}.
This is obnoxious, and makes the result much harder to utilize. How can I
avoid this? I tried deleting
Begin["`Private`"], but then I got a completely crazy result.
What should I do?
