Now I see why it does not work.
But put your mind in AS (which should be the language that I am  actually programming with...

Because of the above I would not write

log zdate
zdate is a date

Which is the same as

log "Today is "& (current date)

that really does not work in ASOC's example above.

That is what I mean by no men's land.

Now, that is a nugget. I was trying  to get description to work but I did not know how.

I agree. The hard part is understanding to walk on the border where you not really in any particular side.

This conversion has proven difficult for me.

It does a lot.

Thanks also for the youtube videos, but, I have one more question, how do I get the weekday of a date.
the functions I tried, I was not successful.

I tried (don't know if I did it right.

components:fromDate:
firstWeekday

setWeekday: --- but this is the opposite of what I want


Thanks
