Is it possible to get the date format of the current page? So that I know that @dateval gives me the correct value.

format or frequency? @pagefreq give the frequency.
Format is machine based, not page/file based.

I was thinking date
format. On a typical quarterly page, I'd like to get back "YYYY[Q]Q". I have often found code like this
Code: Select all
%old_date_format = @word( _
"YYYY YYYY YYYY YYYY YYYY YYYY YYYY YYYY YYYY YYYY YYYY " _
+ "YYYY[S]S YYYY[Q]Q YYYY[M]MM " _
+ "DD/MM/YYYY DD/MM/YYYY DD/MM/YYYY DD/MM/YYYY DD/MM/YYYY DD/MM/YYYY", _
@wfindnc( _
"20Y 10Y 9Y 8Y 7Y 6Y 5Y 4Y 3Y 2Y A " _
+ "S Q M " _
+ "BM F T W D7 D5", _
@pagefreq _
) _
)
%new_date_format = "YYYY[M]MM"
%date_in_new_format = @datestr(@dateval(%date_in_old_format, %old_date_format), %new_date_format)
which feels unstable and could be avoided if EViews supplied something like @pagedateformat to use instead of the unwieldy (and incomplete) expression for %old_date_format.

By "machine based", do you mean that it depends on the locale of the machine?

No, it is a global setting in EViews.
I think there's probably an easy way to do what you want, but I don't understand, yet, what you're trying to do.

I want to be able to take a date string specified in the format of current page and then unambiguously convert that string to a date value.

@dateval usually just figures it out without needing a format

Indeed. But then once in a while, it doesn’t. And then it’s harder to build something dependable on it.
