how to stop execution in for loop

[ddd sh]

Hi all,


I am working on a c source code nearly 2000 line .  it contains one big
for( i=0; i< 200 ; i++ ) loop of around 600 lines
could any tell me how to  break  the execution of prog    when the  value
of   i  is  50   in for  loop so  that i can  check
inside the loop.



Thanks..
