HELP NEEDED: Consolidating SAS Code

Hello fellow SAS users.
I need help consolidating a SAS code that needs to be run for different categorical combinations.

 

For my purposes, there are three categories: Industry, Year, and Country. The following code is being used to calculate a market share variable, and it works. I last used this code about 1 year ago, at which point it was easiest to just copy/paste this code, which already executes the calculation by industry, with modifications for each Country/Year Combination. 

 

As you can see in the current code, the third DATA step deletes any observations that are not in the first alphabetical country, Austria and for any years other than 2002 (the earliest year). As written, I have to run this code over 500 times for all of the country/year combinations. 

 

I would like assistance that will run this same procedure for each Year/Country/Industry combination silmultaneously. 

Any help is appreciated!

Re: HELP NEEDED: Consolidating SAS Code

Can you provide some dummy for 3 countries and 3 years so we can get a better handle on what is actually going on? This link:

https://communities.sas.com/t5/SAS-Communities-Library/How-to-create-a-data-step-version-of-your-dat... has instructions on how to create data step code from a SAS data set that you could paste into the forum or attach as a text file so we could create data to test code against.

 

I have a sneaking suspicion that Sorting the main data by country and year and then doing things using BY Country Year and some First.country and First.Year code may handle most of this.

Re: HELP NEEDED: Consolidating SAS Code

Certainly; the attached Excel file has data for three firms, each in a different country, and across three years for each.

 

I think your idea of the solution may indeed be that simple. It's just that I haven't LOOKED at this in almost 2 years, so it is rather difficult to think about doing anything other than hitting the "Run" button. 

 

I appreciate your time.

Re: HELP NEEDED: Consolidating SAS Code

You actually need to read what people are posting. @ballardw gave you the link about how to post data here. DO NOT use Excel.

I did read what he said, but for the small sample data he requested (9 observations), it seemed much simpler to provide a dummy version of the data. @ballardw if you are not able (or permitted?) to use the Excel file, is there a faster way I can share this small dataset with you?

 

Alternatively, @ballardw I understand the end result necessary after visiting the page you suggested. That is, you want the SAS code that would "write" this dummy data set. I can do that without the macro and will add it once I have done so. 

 

@KurtBremser Franky, I do not use macros; while I understand their usefulness I do not have the skill the write them, and they are often not necessary for the type of data I deal with on a day-to-day basis. As a result, implementing pre-written macros is often a failed effort on my part.

Re: HELP NEEDED: Consolidating SAS Code

About your problem:

Identify the items in your code that you would have to change

Put those items into macro variables and use them in your code

Once the code works, wrap it into a macro that accepts the variables as parameters

Store your parameter combinations in a dataset and use call execute() to run yor macro for each combination.

Hey guys, I just figured out a solution that circumvents the "code" itself. But thanks for the help!
