Am I misremembering how RAND works, or is the documentation on AYAYA wrong...? I thought if you put in RAND without an argument, it would generate numbers up to the integer limit 
I tested it on a ghost with an older version of YAYA too, and it seems to be behaving the same there...
@Zichqec The manual was incorrect. My apologies.
If the parameter is omitted, the result is RAND(100).
@ponapalt Thank you! That's good to know, I must have mixed up RAND with something else, or I have a false memory
It seems that someone wrote wrong RAND document a long time ago.
I think I am not verifying this document enough, because the YAYA source code says it behave same as RAND(100) if parameter is omitted. Sorry.
@ponapalt It seems this information made it into my YAYA guide as well, apparently I didn't vet it properly I should have checked that too, so it's on me as well.
I'm still planning to go through and do some work on AYAYA when I have time, I'll try to test stuff and note any discrepancies that I find
