The full name of a NetSolve problem has two parts:

the

*path*, andthe

*nickname*.

Let us demonstrate this with an example. The problem nicknamed
`ddot`, which computes
the inner product of two double-precision vectors, has the
full name `/BLAS/Level1/ddot`. This problem can be found
in `$NETSOLVE_ROOT/problems/blas`. This full name
has two purposes.
First, when we display a list of problems,
they are sorted alphabetically by their full name, and the
problems are grouped by "directory". Second, by convention, the
first element of the full name (e.g., ` BLAS`) is the
name of the numerical library containing the operation (problem). This
convention
has proven to be useful, as seen in the Section called
