Read binary file with line delimeter

For the first 2 strings, does the 'f' always appear at the end of the string, or can 'f' appear anywhere in the string? Is it just the 'f' at the end you don't want or 'f' that appears anywhere within this 16 bytes?

PS I think the 'f' always only appears at the end. Can you confirm.

PPS In the preliminar output does it start with a '|' and the various parts separated by '|'?

Hello 2kaud,

Yes, the "f's" are used to fill the substrings when the 16 bytes are not completely occupied by numbers (0 to 9), then the "f's" appear always from rigth to left of each substring and could appear one or more "f´s".

Instead of use "," as utput separator, the "|" is only the separator I'd like to use in the output.

I've tested the code and the output with small file I've uploaded in previous post and I get:

1,|532064450189340|81474549232|,0015000A48
2,|532064450189341|81474554768|,0015000A48
3,|532064450189342|81474557521|,0015000A48
4,|532064450189348|81477380427|,0015000A48
5,|532064450189349|81474663128|,0015000A48

where the first column is block number, 2nd column is first string, 3rd column is 2nd string, but is appearing a 4th column that is not supposed to appear. The 4th column should be the first substring of the sub-block if exist.

So, if only first 2 strings are processed currently, the output expected is:

1|532064450189340|81474549232
2|532064450189341|81474554768
3|532064450189342|81474557521
4|532064450189348|81477380427
5|532064450189349|81474663128

Thanks for the help 2kaud.
