Thanks everyone, I am thinking of Data Structures as taught at University.
I bought this recently and hope to use it with other languages.
Fundamentals of Data Structures in Pascal book.
If I understand correctly Data Structures is taught second after introducing a Programming Language.
Unfortunately, I did not get to Data Structures much in school. In High School it Bubble Sort and Binary Search. In College it was Bucket Sort.
I have seen a book for C64 called 64 Data Files and am interested in what it says. It would be nice to make my own file types.
