Hi for all,

I have three problem with my three parts of program
a) when i use the command manually series d01=@daycount("1"), ..., series d07=@daycount("7") it work but by loop it doesn't work i receive an error message. for the second part i would like to make x01=d01-d07, x02=d02-d07,....,x06=d06-d07. b) when i use series d_01=@daycount("1 5"),.., d_01=@daycount("3 7") it work but by loop it doesn't work. could you help me please, any help would be grateful.
Kind regards.

The function @daycount("weekday range") takes on a string argument. Thus, your loops will never work because you're feeding a numeric value where a string should hold. Here's the code you're looking for:

Hi,
Thank you for your response. :D
1/i get error message when i run the program. " D08 is not defined in "SERIES X0!J=D08-D07"." but i have not generate d08. 2/i get error message when i run the part 3 this " D01=@DAYCOUNT(@STR(1) @S is an illegal or reserved name in "SERIES D0{!M}=@DAYCOUNT(@STR(1) @STR(5))"."

In (1), inside the second for loop you've used !i instead of !j.

In (2), you need to concatenate strings together with the + operator. @str(!m) @str(!n) should be @str(!m) + " " + @str(!n), since you need a space between the two numbers.

it works 100%. :) :D
thanks you so much EViews Matt & EViews Mirza.
a last question: how can genarate series contained number of weeks in month or in quarterly?

How would you define the number of weeks in a month? How many weeks were there in April 2017, for example?

Hi,
I see what do you mean Mr startz. Got it!

i would like to loop with three different ways by @daycount:

1)the loop below generate 49 series, i would like to generate just 7 series d_mon_01,...,d_sun_07.
2)manually it work d_mon=@daycount("mon"),..., but with loop i get error message.
3)when i make this manually it work series d_mon_thu=@daycount("mon thu"), but with loop i get error message:
4) could i make two series (frequency monthly) contained the number of weeks and fortnight?

Again, you are confusing string variables and numeric values. @daycount takes on a string argument. However, this time, your loop is running through %d which are already in string format. You cannot use @str(%d) @str() converts numeric values to strings, but %d is already a string. Secondly, to get your naming right, you have 49 series because you are creating a nested loop each with 7 iterations. Thus, 7x7=49. That's clearly not what you want. What you want is to have an additional index that updates by 1 every time you switch to a new loop iteration in %d. Thus, you initialize this index at 0 and then you update it every time the loop repeats. So, the code you are looking for is this.

Thank you EViews Mirza.
1/the code below it work but it generate 9 series just i need this: d_mon_thu_01, d_thu_fri_02, d_wed_sat_03
wfcreate m 1976m01 1990m12
!i=0
for %m Mon Tue Wed
for %n Thu Fri Sat
!i=!i+1
series d_{%m}_{%n}_0!i=@daycount((%m)+" "+ (%n))
next
next
2/ and for my question about weeks and forthnight?

You don't want to use nested loops because you don't want every combination of your inner and outer loop values. However, EViews' for loops can iteration through several values at the same time:

Sorry i haven't seen your reply. thank you.
how can loop like this: d_Mon_Thu_01, d_Thu_Tue_02, d_Tue_Fri_03, d_Fri_Wed_04, d_Wed_Sat_05.

The quick-and-dirty way would be to change the list of days in the for loop, e.g., Mon Thu Thu Tue Tue Fri ...

Something more principled might be:

I understand, thank you so much.
for my question about weeks and fortnight, there is no solution.
how can transfer the every last obs of week in month and date corresponding in the month from page freq weekly to the page monthly freq.
series date_lastw, series obs_lastw

How can import the date and the value corresponding from my page weekly to my page monthly?
e.g. the date of the last week for every month and his value.
same for the fortnight frequency.
any help would be gratefully appreciated.
