Basically, I have a large SAS assignment which I know how to do by hand, but I'm sure there are lots of useful shortcuts that I don't know about which could make it less cumbersome!
I have a Word document outlining about a thousand values that have been divided into 16 categories. I also have a SAS dataset in which each row can contain up to 10 variables containing the values that have been categorized in the Word document.
The only way I can think to do this is to code by hand:
If var1 in (abc, def, ghi, jkl) then category1=1;
else if var1 in (mno, pqr, stu, vwx) then category1=2;
else if var1 in (zzz, zyx, wvu, tsr) then category1=16;
if var2 in (abc, def, ghi, jkl) then category2=1;
else if var2 in (mno, pqr, stu, vwx) then category2=2;
As you can see, this gets very cumbersome very quickly, as I have 10 vars containing the values and 16 categories. Any shortcuts would be much appreciated!

You'd have to provide more detailed examples for more detailed help. But generally, if its categorizing or recoding, look at a merge, hash or proc format instead of multiple if/then statements.
If you're doing the same thing across a whole bunch of variables consider an array as well.
