LOOKUP1.BIN contains the lookup table for Script Triggers, which abstract script ID numbers so that each script referenced in Custom receives a permanent trigger ID linked to its name, while its actual ID number is free to vary and be autoassigned (by HSpeak). The "1" on the end of the filename is a relic; there are no other trigger lookup tables (initially it was planned to add more).
The lumps are in binary records 40 bytes in size where record n is the data for the trigger of ID n.
|0||INT (1)||Script ID number, 0 if not used|
|1-19||FVSTR (1i+36b=38b)||Script name|
