Re^3: finding the status of the program being called from perl

You should choose $sel->can_read for the file handle you are reading from (i.e. the filehandle that the other process is writing to).

The filehandle you should test to see if the other program is waiting to read is the filehandle you write to.

matija, thank you. but it's not working. i think it's more complicated than it sounds? i mean, using IO::Select. are we supposed to go into a while loop? too confusing. but not all hopeless, i think i found another solution. i think i will try bioperl. anything you want to do, if you search long enough, you will find someone else has already done it. thanks anyway. take care. see you.
