ULX

The ulx file extension is associated with the Glulx and used for its data files.

Glulx is a portable VM, like the Z-machine. Unlike the Z-machine, it uses 32-bit data and addresses, so it can handle game files up to four gigabytes long. Also unlike the Z-machine, it has native support for Glk I/O, so game files can use any capability Glk provides. However, like the Z-machine -- again -- you can write games in the Inform language and compile them to Glulx game files.

The ULX file extension is related to the CLAN.

The acronym CLAN stands for Computerized Language ANalysis. It is a program that is designed specifically to analyze data transcribed in the format of the Child Language Data Exchange System (CHILDES). Leonid Spektor at Carnegie Mellon University wrote CLAN and continues to develop it. The current version uses a graphic user interface and runs on both Macintosh and Windows machines. Earlier versions also ran on DOS and Unix without a graphic user interface. CLAN allows you to perform a large number of automatic analyses on transcript data. The analyses include frequency counts, word searches, co-occurrence analyses, MLU counts, interactional analyses, text changes, and morphosyntactic analysis.
