Merge step1 step2 ... step27

[Lupacante]

Hi all,

is there a way to merge a lot of datsets with increasing suffixes?

data mydataset;

     merge step1 step2 step3 [...] step27;

     by myvar;

run;

is very long to write.

data mydatset;

     merge step1 - step27;

     by myvar;

run;

doesn't work...

any suggestions?

What version of sas are you using ? I can run your code.

SAS enterprise guide

Merge statement supports data sets lists, so It should work.

Please elaborate more on  "doesn't work...". Did it throw an error message or it didn't work the way you expected? Do you have the log? More details would be helpful.

So you are using the Eguide, but what version? 4.3/5.1 or 6.1?

Regards,

IT's 4.1.

It doesn't run at all, just gives an error message.

It's ok though, I've solved it by writing a macro around it as RW9 suggested.

Thanks for your answers

With a macro:

data mydataset;

merge

  %macro datasets;

  %do i = 1 %to 27;

  step&i

  %end;

  %mend;

  %datasets

;

by myvar;

run;

But you don't need that, as others already said, the set1-set27 solution works at least in 9.2.
