I have a file that is being used to lock a process that contains only the values of 1 and 0 in it. I have tried opening the File and $value = <file_name> as well as foreach(<file_name>){$value = $_}. I do not only want to `cat $file_name` because if the file is unreadable I want to be able to trap the error. What are my alternatives? I need to be able to do the following but for some reason it is not working... 

STAGE_DIM: if(not(open(process_lock, "+>$proc_lock"))){
                    goto STAGE_DIM;
                    sleep 1;
                }
                $lock_val = <process_lock>;  #`cat $proc_lock`;
                print "Value=*$lock_val*\n";
                if( $lock_val == 1) {
                    close(process_lock);
                    sleep 1;
                    goto STAGE_DIM;
                }
                else {
                    ...
                }

The Value read is always "". The only way thus far, I have been able to read the contents of the file was to $lock_val = `cat $proc_lock`; but this leaves the chance that the file could be unreadable because another Process has it locked open. Any ideas would be appreciated. Thanks. rheaton
