Hey !!! Thanks a ton!!! With notepad , I could finally call the other script!! Thanks again for helping , Cheers Bucchi

And the lesson to be learnt here is that before investigating on supposed problems with a.pl calling b.pl, one would better make sure that b.pl works fine in the first place. Again, there may better strategies than resorting to system, from using do to making the called script into a real module. But this is probably stuff better fit for another thread...
