Sir,
Thank you very much, but lastly I want to ask you about:
c=b(3:7);
Acually the below one is not a fixed one, but it will vary:
1. Alarmtype1 heater volt:1670890
2. system error:5480
3. Alaram, voltage, event ID:46754
4. warning, id:15643
5. warning current, event id:76542
I mean 1~5 will vary, may be some time 1~3, some time 1~4, or some time 1~8 or what ever. That is why instead I want to stop when dotted line appears (--------) for this Data2 storing. 
One more thing, I have to read multiple text files from the directory at the same time. I attached herewith four text files for example.
May I humbly request you to kinldy help,
Sincerely, 
Your's
