Get Substring

Expression (pure) Strings 3 in 1 out ⬚ 1x1

Extracts a number of Unicode characters starting at an index; negative starts count from the end, useful for prefixes and file extensions.

The supplementary gate_docs.json calls this “Substring”. The primary inventory name (Get Substring) is shown here, matching the in-game UI.
