how to run multiple program in one program?

[Liu]

Hi,

I created quite a few modelling programs, say model1.prg, model2.prg... and I want to use a master program
to control what program to run everyday. For example, in masterprogram.prg I wrote commands as below:

run path:\model1.prg
run path:\model2.prg
run path:\model3.prg



The problem right now is that once the first sub program is finished, it doesn't procede to run the second program. The entire
master program stops now at model1.prg.

How can I let eviews continue with the rest of the program?

Thanks in advance.

Use include or better yet exec instead of run.

[Liu]

Yes Glenn I used the exec now and it seem to run one program after another according to the list in my masterprogram.

I still have slightly a problem: if one program in the middle has some errors and paused, can I program the mastery program so that
it can proceed to the next program? what I mean is like this: suppose that the master program is :
exec model1.prg
exec model2.prg
exec model3.prg

what I'm trying to do is that in case something's wrong with model1, it dones't stop there, instead it proceed to run model2.
is there a better way other than setmaxerror?

Million thanks.

Use @errorcount to check if a line caused an error, then "return" if it did.

Is there a way to run the execute function across a bunch of programs in a specific folder? I have dozens of variations of models that I have to run on the same data. I would like to just group them into folders and run all of the programs in a folder as needed.

Thanks for the help.

[EViews Gareth]

Just make a program that executes all the programs in the folder.

[Davidth]

Thanks for the reply Gareth, but I only know how to get it to run specific programs that I specify directly. I was looking to find out how or where I can learn how to direct it to run a group of programs in a folder.

I looked through the Command Ref and Obj Ref guides and did not see an explanation for how to have the execute command run a series of programs from a single folder. Thanks again for your help.

Use the @wdir function to make a list of all files in the folder, then loop through them one at a time, execing each one.

Something like:

Code: Select all

%dir = "c:\temp" %list = @wdir(%dir) for %j {%list} if @upper(@right(%j, 3)) = "PRG" then %file = %dir + "\" + %j exec %file endif next

Thanks so much Gareth. This is my first job that requires me to get into this much detail with programming and I can honestly say, I do not think I would have ever figured that one out.

Hi Gareth, I'm using the code above to write a program that takes in a sample period and then runs a list of programs, and saves down the work files somewhere. I'm using the 'exec' function to run the programs and the 'wfsave' function to name the work files that each program run creates. I have a very simple question(!) - I have said 'wfsave "C:\my documents\testfile\JPY" how can I get it to time stamp the work file so that it calls it JPY_10/12/2015...ie so that it adds todays date at the end of the name. thanks!

[cc100]

And one more question: I have a number of programs, which start with the following code:

%my_startdate = "31/10/2003"
%my_enddate = "08/12/2015"
'*********************************************************************************************************************

wfcreate file1_jpy d5 %my_startdate %my_enddate

All the program files start with the same code, i.e: they all take in a start and end date (except they have different names, file1, file2 etc..)

I want to write a master program file that takes in a start date and an end date and feeds that into each program, runs each program and then saves the workfiles. So I have the following:

%my_startdate = "31/10/2003"
%my_enddate = "10/12/2015"
'*********************************************************************************************************************

'exec "C:\documents\test1\file1_jpy.prg"
'wfsave "C:\documents\test1\jpy1.wf1"

'exec "C:\documents\test1\file2_jpy.prg"
'wfsave "C:\documents\test1\jpy2.wf1"

'exec "C:\documents\test1\file3_jpy.prg"
'wfsave "C:\documents\test1\jpy3.wf1"

The issue I am having is that the master program file cannot overwrite the dates in each individual file. So I would like to know the code that allows me to feed in dates into each individual file please. (and the other question of how to date stamp each work file so that it reads "jpy1_101215"

Thank you

Code: Select all

@datestr(@now, "yyyy-mm-dd")

returns the current date as a string.


To pass information onto child programs you'll want to use program arguments or program options.

HI Gareth, thank you - why doesn't the following syntax work: wfsave "C:\documents\test1\jpy3_" + %date +".wf1"

it just produces the file name jpy3_.wf1

[cc100]

sorry forgot a bit of the program! where %date = @datestr(@now, "yyyy-mm-dd" )

[EViews Gareth]

Create the file name string before the wfsave command
