non-destructive interrupt of GP program

["Max A." <maxale@gmail.com>]

For simplicity assume that I run in GP the following program

for(i=1,10^20,n=i)

and want to interrupt it at some point and learn the value of n.
If I just press ^C, the value n will be lost:

? for(i=1,10^20,n=i)
 *** for: user interrupt after 1,888 ms.
? print(n)
n

Is there a way to interrupt computations such that the value of
valuables is preserved?

Thanks,
Max
