That was not what I was trying to ask for. Generally I just run my
data analysis tools as "filters", where I can manage with processing
one line (or a few lines) at a time.

The important part is to have the checking of the headers and the
generation of Put_Line and Get_Line procedures automated based on a
record type (and not too much more). Since I need records (for type
checking) and not just simple arrays, I can't manage with a generic
package, but have to put some code generation into the system (or can
I play some tricks with streams?).

I'll see if I can find the package in Charles, which does this.

I have that already.
