BibTeX uses RPN in its style definition (.bst) files. Diving into the standard style definition files gives you a taste for how long the system has been around, with many comments dated in the early nineties. Here is an example of a function:
FUNCTION {emphasize}
{ duplicate$ empty$
{ pop$ "" }
{ "\emph{" swap$ * "}" * }
if$
}
I believe this is also somewhat similar to the PostScript language.
