In PostScript, you can "initialise" an array with a value with
/Encoding [
255 {/.notdef} repeat
] def
% Set array entries individually
Encoding 0 /asciicircum put
Encoding 34 /quotedbl put
% Print contents of array to stdout for inspection
Encoding ==
Compressed, that becomes:
/E[255{/.notdef}repeat]def E 0/asciicircum put E 34/quotedbl put
I use an enhanced alternative
<https://github.com/Alhadis/Stupid-Post-Tricks/blob/09a98036abba913c0766e60d1bac2008e7d71c5c/inspect.ps>
to PostScript's built-in `==` operator, which is imported with:
%!PS
(/path/to/inspect.ps) run
% Usage:
<< /foo (Bar) /baz (Qux) >> ===
(Check gs(1) for details on the library search-path and invocation syntax).
