hi all,
what if i have to use,
spawn, 'c:\hi\what to do now\something.exe'
now the space that is in "what now" causes a problem. Thats the reason i was
against spawning. i can solve that by just moving all the files into the
working directory and just use
spawn,'something.exe'
thats how i have solved the problem now
sincerely
