Thanks to everyone. I read ? sprint and the following is best I came up
with. If there are ways to collapse the lines I'd be glad to know.
Otherwise, I will live with this. Thanks again.
cat(sprintf("\ntol = %e",mycontrol$tol),
sprintf("\nreltol = %e",mycontrol$reltol),
sprintf("\nsteptol = %e",mycontrol$steptol),
sprintf("\ngradtol = %e",mycontrol$gradtol))
tol = 0.000000e+00
reltol = 0.000000e+00
steptol = 1.000000e-08
gradtol = 1.000000e-10

Hello,
There's also ?message.
msg <- sprintf("(tol,reltol,steptol,gradtol): %E %E %E %E",
mycontrol$tol,mycontrol$reltol,mycontrol$steptol,mycontrol$gradtol)
message(msg)
Hope this helps,
Rui Barradas

Thank, Boris and Ivan.
The simple command suggested by Ivan ( print(t(mycontrol)) ) worked.
I went along with Boris' suggestion and do/get the following:
cat(sprintf("(tol,reltol,steptol,gradtol): %E %E %E %E",mycontrol$tol,
mycontrol$reltol,mycontrol$steptol,mycontrol$gradtol))
(tol,reltol,steptol,gradtol): 0.000000E+00 0.000000E+00 1.000000E-08
1.000000E-12
This works great. Thanks.

??? t() is the transpose function. It just happens to return your
list unchanged. The return value is then printed to console if it is
not assigned, or returned invisibly. Transposing your list is
probably not what you wanted to do.
Returned values do not get printed from within a loop or from a
source()'d script. That's why it "works" interactively, but not from
a script file.
If you want to print the contents of your list, just use:
print(mycontrol)
Or use some incantation with sprintf() if you want more control
about the format of what gets printed. Eg:
cat(sprintf("Tolerance: %f (%f %%)", mycontrol$tol,
mycontrol$reltol))
etc.

Printing this in a main program causes no problem (as shown above).
But, using the command t(mycontrol) the line gets ignored.
t() doesn't print, it returns a value. In R, there's auto-printing in
the toplevel context (see ?withAutoprint), but not when you move away
from the interactive prompt. I think that it should be possible to use
an explicit print(t(mycontrol)) to get the behaviour you desire.
