Just a small problem : you can create an alias with five characters in a program, but it reports "illegal scenario alias" if you access it in menus.

Also, the subsequent window can refuse closing.

Thank you. I reduced the name length and it solved the problem (actually it was not my model, personally I try not to use more than 8 characters, sometimes 1 or 2). This model complies with a national accounts framework...

Hello from Paris, In my experience I find it modre convenient to create a time variable called, let us say, t, with rhe value of the year. For quarterly models I start with the year for the 1st quarter, and increment by 0.25 for each quarter (this does not work if 1/periocity is not a decimal fracti...

Hello,

I get this message:

TC_D51CRDS_TRAV_S14E3_SC already exists in "DO_ _MODEL.SOLVE(O=N,I=P)"

I do not understand why a series existence is s problem for the SOLVE statement.

Maybe the name is too long???

About the pagedelete statement First, you cannot use @isobject to test if a page exists and delete it. I understand a page is not an object but an exception could perhaps be made. This means that if you want to make sure a page does not exist by destroying it, you get an annoying error message if it...

Sorry, I have to admit the message was not so clear. The problem occurs whan the changed string contains the string wich is to be changed, for instance when you change "b" into "bc". With the text : -------- aaababaa -------- You get first : aaabcabaa then : aaabccabaa aaabcccaba...

A very simple (stupid?) trick. Many models include conceptually null variables (like exports from a country to itself.... When you compare the relative difference between two simulations, or simulations and historical, EViews will divide zero by zero, giving a NA value and an annoying error message....

Hello, Some time ago I presented a method which allows simulations to reach given targets for a set of endogenous variables , through the automatic computation of the same number of exogenous elements. My post had very little success, which surprised me as I often met people who had trouble with thi...

A stupid trick... If you start a session by opening a file other than by using the "file open", for instance by using the list of the last files accessed, or by clicking under Explorer, you might not know (or are too lazy to type) the name of the directory. If you want this directory to be...

Hello, When many elements are open at the same time, only a limited set can be accessed, from a "small" window, and you need to scroll to reach the others (the last opened or created). Generally, these will be the most important at the time. Would it be possible to order elements starting ...

Sorry, this bug seems to have disappeared with EViews 6. I just ran the very same program on the very same files with the two versions. 6 works, not 5. In an equation for labour productivity : PL = Q / LF Version 5 actually computed : PL = Q(-1)/LF Both Q and LF appear as lagged in other parts of th...

Hello,

Any time I edit a .prg file. But it seems to happen essentailly with large prgs. Like 20k+. And if I repeat the Ctrl-V quickly.

I thought you meant in a model identity. Of course if the equation was estimated the problem is different.

But if you want the variable to be positive it is probably that it should be so by nature (like the nominal interst rate, or GDP), which means it is positive on the sample period.

Hello, In case somebody is interested, I have written a subprogram which allows to switch two sets of variables (of equal size) between endogenous and exogenous, over any period of time. It is based on Newton's method. You just have to define the two lists of names, and give the values for the new e...

Hello, You could add an equation creating a new variable x as : x = y *(y>0) and use x as the endogenous. Take care, Jean Louis Brillet. Actually, the problem is when your model uses the logarithm of the variable. In this case it needs to be strictly positive, and probably different enough from zero...
