Advents of Code (programming challenges)

[Thomas Okken]

There are no examples on my web site, but the functionality is documented near the end of the section "Functions", under https://thomasokken.com/plus42/#equations.

An example of a named function calling itself could be

FAC(N):IF(N<=1:1:N*FAC(N-1))

The same syntax can be used for calling one function from another.
