unable to access namespace after breaking into fit

[<pl...@pi...>]

Hi,

having had to interrupt the execution of a fit command, I discover I can 
no longer access the variable name space.

gnuplot> print  first_start
gnuplot>

note it does not show it undefined but returns a null result.

if I do 'show all' it does display the expected values.

gnuplot> show all

...
         first_start = 1820
         last_start = 1974
....

regards, Peter.
