Hello,

my application now needs to read a file. I've already my old C function for this purpose. Because I want to make available the source code of the new rewritten application I would like to use all the U++ facilities and get rid all C functions and its flavour.

The question: at some moment my file become formatted and ';' delimited... like this:

NAME;            COUNTRY;BIRTHDAY;G;TITLE;IDFIDE;ELOFIDE; IDNAT;ELONAT;K;ISAVAL
AAAAAAA             ;---;00.00.00;m; GM;       0;    0;       0;    0; 0;1
BBBBBBB             ;---;00.00.00;m; GM;       0;    0;       0;    0; 0;1
CCCCCCC             ;---;00.00.00;m; GM;       0;    0;       0;    0; 0;1
...

I need to extract the field beetwen consecutive ';' in each row-record. In the past I've used the strtok() function. Is there something equivalent in U++ ? I've investigated all the code available but without success.

I've found a C++ token function here

I'll try to adapt it in U++ if there is not yet one.

PS: BTW, I'm going to use the cin operator to read the txt file. Please stop me if there is some smartest way to do it.

PPS: I spent the afternoon to learn I/O in C++. Surfing the web I found this reference that says something (but not useful in concrete sense) about serialization
http://www.parashift.com/c++-faq-lite/serialization.html#faq -36.11
I reminded that U++ has such feature. I wonder if it can be useful in my case or it is an argument too advanced for the moment and/or not useful for such application (it needs to save data at some moment inside 2 text files).
