I spent 20+ years in my day job programming in BASIC on OpenVMS without using line numbers or GOTO's. Yet the first thing I did here was fall back to my childhood Sinclair/BBC BASIC of trying 10 PRINT "Hello" 20 GOTO 10
Software for the Agribusiness sector - mostly around the manufacture and selling of animal feed. So data entry, processing, interfacing, reporting. We had the legacy system which was a text terminal interface, as well as a newer browser based system that interfaced via webservices to the OpenVMS BASIC code. After 40 years it went end of life at the end of last year.
I'm not surprised that the system lasted that long! VMS is legendary.
I've looked through the documentation for OpenVMS BASIC and it does seem like it was a nice platform.
The entire VMS system appears to be quite a comfy environment to have worked in. (DCL, help system, documentation, standard libraries, multiple languages (Pascal, C, BASIC))
