Hello!
Alright, to begin with I have experience in several programming
languages, from assembly to OOP, and now I find myself delving into Ada.
I am taking a class on Ada and I am absolutely stuck in a lab. I need
to open a comma delimited file, read it's contents into a variant
record, display the contents of the record, and then get the next
record. So far I can open the file without a problem, it is the reading
the comma delimited records into the variant records where I am hitting
a wall. I would tag on my code with this message, but right at the
moment it is a garbled mess from me trying a bajillion different
approaches to the problem.
Essentially, I am looking for pointers on working with variant records.
Any information will be hugely appreciated!
Thank you in advance!

If I understand correctly, you are opening a text file, where each
line is a sequence of fields, separated by commas, and you want
to read a line at a time, store the fields in a variant record,
and then display the record, for each line.
I find I can't advise you without knowing which feature of the input
file is creating a need for variants of the Ada record. Is the
number of fields per line variable? Is the type of the fields
variable (number, string, ...)?
