SAS-How to split a string into an array

Asked by herbalizer in SAS, MS SQL Server, MySQL

Tags: SAS or SQL, SAS Version 9.1.3 SP4

OK, I was able to transpose all distinct values of a column into separate columns, thanks to KendallTech and Wolfen351, now all I want to do is the complete opposite.

I have a character string with elements separated by a semicolumn (;).  I want to take that string, and split each element into an array (or just different columns) and use the ";" as a separator as each element has a variable size.  That's it.

ex.: String_Var = EL1 ;EL2 ;EL3; etc ..

Result wanted :

Column1    Column2     Column3
EL1            EL2             EL3

SAS Help is terrible !  I can never find what I'm looking for in there, and I noticed that there is not a lot of support for SAS programming issue (even @expert exchange - which is still the best place to look for info)

I would prefer an answer using the SAS programming language but SQL statement in the following format could also work:
proc sql;

code

quit;

I will see if I can craft something more definitive, but you could write the string to a file, and then read it back in as a delimited file.

Data test;
infile "c:\test.txt" dlm=";" dsd truncover;
input
String1-string10 :$char10.
;
run;

This might get you started.  I will see what I can do programmatically within the same SAS program.

I think that this example may do roughly what you want:-

data test;
     array sarr(3) sarr1-sarr3;
     str_ex='EL1 ;EL2 ;EL3;';
     do i=1 to 3;
         sarr{i}=scan(str_ex,i,';');
     end;
run;

By the way, I find the SAS Help documentation extremely helpful and generally very well written. I guess that comes from having used SAS for over 18 years.
