Dear All

I have a text file with more than 300000 of lines like the following:

1 E E E
2 C D
3 B E D
4 C E D
5 D E

I am looking for an automatic way of transforming my text file into
another one with the format

1 E
1 E
1 E
2 C
2 C
3 B
3 B
3 D
4 C
4 C
4 D
5 E

Any ideas?

Thanks in advance,

Paul

I am guessing that the transformation should have been
1 E
1 E
1 E
2 C
2 D
3 B
3 E
3 D
4 C
4 E
4 D
5 D
5 E

I'm not that great at scripting which somebody else will no doubt suggest, so personally I'd write a little C/C++ application to do it. I've got a string parsing function that I wrote to split a string into white space delimited fields and return a count of the number of fields, which would be a good starting point for this.
