What do you mean? I dont really understand what you are doing here

            type tElement = record element_type: tType; number: integer end;

That second line confuses me. Records are a bit confusing. I read my textbook on them, but they are still confusing me. I am not really sure what my program is doing. Like, I can't understand the record part of it. Does my equation from the input file go into the record? How would I assign numbers from my file into "num" in the record, and operators from my file into the appropriate places in the record?
