I started programming in GW-BASIC on an IBM PC clone running MS-DOS. Back then, many so-called home and business computers came bundled with a BASIC interpreter, mostly made by or licensed from Microsoft. They all looked similar. You were greeted by a screen with a READY or OK prompt and a blinking cursor waiting for your input. The “screen editor” and interpreter were all in one in the true sense of the word – they weren’t bolted together like the separate text editors and interpreters/compilers we use these days…
This is where I’d humorously link that maniac who wrote a program exclusively using MOV, of any amount of quotation or clarification could convince a modern search engine that “movulator” does not, in fact, mean “modulator.”
