I don't know what Nancy Said (Although I doubt she said this). I have been coding since the early
70's (1973 Digital pdp8 os/8 with massive a 128k that filled a cabinet). And we used "=". filePro
was out in the trs80's in 1976 - 1977 ? That date is after 1973, (OS/8 Basic (ITT Teletypes),
FORTRAN, (pascal and COBOL -IBM 36 on punch cards!!!)). These all had "=". C (and B )had ":=" or
"==" - still does; C# retained this too.  So the "That's how it used to be doesn't fly".

Additionally filePro was written in "C" or "B" as far as I have been told. That standard is "==".
