This sample file is a set of 30 tables with raw data similar to the table shown below. I am able to read it directly in an hex editor, although it is a very pedestrian way and time consuming.

Here is the first table from my sample file. It contains 14 records.

Code:

14 05 00 00 07 01 40 00 14 05 00 00 12 02 C0 00 
6C 07 00 00 06 03 C0 00 00 00 00 00 00 00 00 00 
6C 07 00 00 03 04 40 00 6C 07 00 00 01 05 40 00
14 05 00 00 04 06 C0 00 00 00 00 00 00 00 00 00 
6C 07 00 00 09 07 40 00 14 05 00 00 0C 08 C0 00 
6C 07 00 00 0E 09 40 00 6C 07 00 00 08 0A 40 00 
6C 07 00 00 0B 0B C0 00 00 00 00 00 00 00 00 00 
14 05 00 00 0D 0C C0 00 6C 07 00 00 02 0D 40 00 
14 05 00 00 1D 0E C0 00 00 00 00 00 00 00 00 00

Let's look at the first record of the table to show you how to read it.

Code:

14 05 00 00 07 01 40

Each record in the table is conformed by 6 fields:

1. First field of the record corresponds to the first 2 bytes, in this case, 14 05. We need to read it from right to left though, i.e., 0514.
2. Second and third fields correspond to the 3rd and 4th bytes and both are 00.
3. The 4th field is a number between 0-29 (decimal) associated to the 5th byte, 07 in this case. Of course in the table we are dealing with the hexadecimal representation.
4. The fifth field is the record number, 1 for the first record and so on. It is associated to the 6th byte.
5. Finally, the sixth field can take one of 2 values only, C0 or 40. Then, we have a 00. Following two bytes correspond to the first field value of next record and so on until the last one.

It would be great if anyone could help me to extract/transform each table from my sample into something more natural to work with (I mean, more natural for humans). For example, a kind of editor for this file or a way to extract a file for each table. Of course decimal numbers instead of hexadecimal would be perfect.

Thanks.
