here I found this page https://forum.pdpatchrepo.info/topic/13087/abstractions-as-creation-arguments-things-i-wish-i-knew-before

I added a bit for extra explaination after looking quickly

mine says divde by zero detected.

because I dont understand expr really, I only do everything without them. which is the same thing. probably - it just looks different. If you write out all of them in english Id try and do it regular and maybe learn it at the same time. write it up and ill try it. otherwise your file is missing "output" object I dont know what library it is. it means dac~ ?

this has a bunch of stuff it uses an older version of pd sometimes but you can work around it , they changed a couple object names.

this is how you convert the other one, I dont really use symbol lists yet. so I looked it up on the help page for pack object.
abcd_rollover.pd

here I made an odometer thing
mod4_rollover1.pd

aaaa aaab aaac aaad aaba aabb aabc aabd aaca aacb aacc aacd

the ones place goes through "a,b c d" over and over and then the tens place changes to b when you hit "a" again. and then when the ones place changes to a "a" third time the tens place changes to "c" etc etc.

if you have a four number set. you would end up with 4x4x4x4 lists right?
so it looks like 0-9999 except that 0-9 is actually a 4 number set instead of a 10 number set. so you count upward and use the numbers as symbols but you only use 4 before rolling over. that might work.
