BankLang playground
A deterministic compiler from BankTS, a small banking language with TypeScript's type syntax, to readable IBM COBOL. The real compiler runs here in your browser: there is no compile server, and nothing you write is sent anywhere. Edit the program, watch the COBOL change, then Run it.
Source
Edit this. It recompiles as you type. Click any line to trace it into the COBOL beside it, or open Run to execute the COBOL and see what it posts.
