This subroutine prints out new information after a successful line search.

Parameters

n	On entry n is the number of variables. On exit n is unchanged.
x	On entry x is an approximation to the solution. On exit x is the current approximation.
f	On first entry f is unspecified. On final exit f is the value of the function at x.
g	On first entry g is unspecified. On final exit g is the value of the gradient at x.
iprint	It controls the frequency and type of output generated: iprint<0 no output is generated; iprint=0 print only one line at the last iteration; 0<iprint<99 print also f and \|proj g\| every iprint iterations; iprint=99 print details of every iteration except n-vectors; iprint=100 print also the changes of active set and final x; iprint>100 print details of every iteration including x and g; When iprint > 0, the file iterate.dat will be created to summarize the iteration.
itfile	unit number of iterate.dat file
iter	TODO
nfgv	TODO
nact	TODO
sbgnrm	TODO
nseg	TODO
word	TODO
iword	TODO
iback	TODO
stp	TODO
xstep	TODO
