Parsing a binary file

[Solren]

Hi everyone,

I have some difficulties parsing a binary file in Delphi (XE2).
My line-by-line parsing code works for a standard text file but fails for the binary equivalent. The file wasn’t generated by me and not with Delphi although it has a quite simple structure - header with structure description (which seems to have an ASCII format in the binary file) and a tab-delimited data table.

I already tried with simple hex conversions and binary read mode although I feel that I’m going the wrong way. I’m not expecting a ready-to-go solution but at least a hint on where to start would be extremely useful.

Here is an example of the data file (both text and its binary equivalent):

Thank you for any help.
