Ex COBOL dev here. Started at NCR on COBOL for minis and mainframes. Then built stuff on Wang VS COBOL for ERP systems until 93. Quite a few other languages since then but been a Product Manager for past 20+ years.

HN is a place where everyone is, so it's reasonable to assume that some Cobol devs may also lurk here.
