Thanks. I will play around with traditional strings to make my own 
simple CSV parser - a good lesson it will be :)

Thanks. I may, in fact, not, due to regulations. I'm playing with ADA 
for my academic course. We've formally just started, but I'm "thinking 
ahead" and doing all future the tasks at home to learn better. We must 
not use external ADA libraries. That's why I'm playing with my own 
parser, which somehow felt right with Unbounded Strings.

The string format is known, its always three columns - but of unknown 
width (in some boundaries, of course, let's say - 100).

I used Unbounded Strings to slice my input by semicolon sign once, then 
slice the rest, and then slice the rest of the rest. I guess I can do 
the same with a simple loop over traditional string to check semicolon 
positions and then simply slice the string with known left/right 
boundaries. Back to code then... :)
