"NEC2 was based on punch cards and an antenna model was described as a series of Cards. These are well documented. Nec2++ replaces these cards with function calls each function call the equivalent of an nec2 card."

Yes, the simulation model is so old and was so successful, modern replacements are modeling their API parameters like the old punch card formats. Is this a form of #retrocomputing?
