I’ve never gotten avaricious small town business types to believe that the cheap thing to do if the proprietary language you spent a lot to buy is EOL is hire some interns from your local Uni who took a compilers class to write an implementation or translator for $0.00 and some good experiences although… it’s true.

Taking a college level compiler class will get you a toy compiler.

Not the best but something that seems impossible to the small town businessman.
