Hello everyone, I wrote these two functions BUTFIRST and BUTLAST (as in
LOGO) butlast: func [series] [
copy/part num (length? num) - 1] butfirst: func [series] [
copy/part next num (length? num) - 1] It seemed to work: >>num: [1 2 3
4]
== [1 2 3 4]
>>butfirst num
== [2 3 4]
>>butlast num
== [1 2 3] ... but unfortunately, when I try to compose functions with
them as in:
>>butfirst butlast num
== [2 3 4]
>>butlast butfirst num
== [1 2 3] I'm very curious to understand why. many thanks jf
