Here is my query:

I want to run a program called "phylip" from perl script. "phylip" is a command line program, that has many sub-programs in it. Typically a phylip program appears like this when executed at command prompt

chak:~$ phylip sub_program_1
sub_program_1: the file "out-file" that you wanted to use as output 
file already exists. Do you want to Replace it, Append to it, write 
to a new File, or Quit? (please type R, A, F, or Q)
.....
(phylip subprogram_2
......
please type R, A, F, or Q) n times

[download]
Every-time I run phylip program, I know exactly when to type what character/string. (In above example I have to type: phylip sub_program_1, R, phylip sub_program_2, R).

My perl script generates files required for phylip program, so it would be cool, if I can automate these steps in perl script itself

Can anyone advice me on how to do this ?

Thanks

Chak
