Hello there! ;-) I noticed that the syntax highlighter file for Avisynth is a little outdated now. Not only the set of core keywords, also the structure syntax got developed further in AviSynth+. So I tried to add some elements to the highlighter INI file.
One piece is that it supports block comments, not only EOL comments '#' like in PHP. One supported syntax is C-like '/* */' but there is also an alternative style to allow nesting which lacks support in PSPad because it would need the implementation of a new comment style class: Asterisks in brackets '[* *]' The full AviSynth grammar / Comments (viz https://avisynthplus.readthedocs.io/en/latest/avisynthdoc/syntax/syntax_the _full_grammar.html#comments ) -- <https://forum.pspad.com/read.php?2,79519,79519> PSPad freeware editor https://www.pspad.com
