That doesn't work. Is there any way to search like a dictionary? input soso -word 1 here 'word searched -word 2 here 'defenition etc

I created a library for compile-time dictionaries called Lowerdash. smilebasicsource.com/page?pid=59 Like I said they are compile time, so you can't change the keys while your program is running. it might be possible to write a mutable DICT in future releases.

I asked the president Kobayashi, he told that such hash was on their TODO list.

A hash is usually done via CHECKSUM function. So, K=CHECKSUM("merringold") R=HASH[K] What I usually do, however, is just sort the array, and use binary search. OTOH, assuming all the keys fit in a string, you can just use the value return by INSTR() ^_-
