Dear Tom:

I have checked the @ seanalDLM procedure. Why does the procedure return [al] and use both [*ap] and [*a] simultaneously. In addition, I would like to know why [ap], [cp], [swp] are used, and whether these parameters are following @ seasonalDLM? If that's the case, when calling @ seanalDLM, the current option is used instead of using parameters according to the procedure. Is it compatible with old code?

So it wouldn't break any old code (it originally used the parameters). The options are the preferred method. I think that's described in the comments of the procedure file.

Dear Tom:

Thank you very much, I understand now. I tried to write a related procedure, so I delved into the internal code in detail.
