Counting in Erlang (how do I increment a variable?)

Question

I\'ve figured out the Erlang-style loops: tail-recursion with functions that take all the \"variables that don\'t vary\":

%% does something, 80 bytes at a ti         


        

Answer 1

Don't use the process dictionary.

The 'normal' loop that you are expecting (ie a for loop or a do while) is usually implemented in a recursive function in Erlang so if you are incrementing a 'normal' counter do it in the function calls like you show up top.

Don't use the process dictionary.

In case you missed, can I just point out that you should not use the process dictionary.
