I think of PostScript as being Lisp, more or less, but with quasi-Forth
syntax, and using arrays where Lisp uses linked lists.  Maybe Lua or
Python is a closer analogy: PostScript has separate array and dictionary
types, like Python.  But it’s extensible like Lisp or Forth.

Aside from the Adobe manual, Paul Bourke has a great tutorial and
reference at <https://paulbourke.net/dataformats/postscript/>.
Nathan Laredo has an amazing collection of PostScript code at
<https://postscriptcode.com/>, which is worth browsing through, and of
course Don Lancaster has lots of interesting stuff at
<https://www.tinaja.com/pssamp1.shtml> and nearby.

Mitch Bradley wrote a Forth *in* PostScript:
