Database (Imported from Excel) contains 'cells' containing a % sign, and cells with no % sign.
Would like to go through entire database, and if NO %, simply DELETE whatever is presently there in the cell. Result, empty cell.
If there IS a % somewhere in the cell (generally at end, such as +2.07%), leave that cell alone.
Another alternative approach would be to KEEP ONLY those 'cells' where there exists the symbol %. All other cells should be deleted. Even better, use RegEx, and insist the % be at the end of the line, such as +2.07%.
Suggestions greatly appreciated.
Thanks!

So if any cell in a column contains text like `%` then SAS will define the variable as character. So you really just need to process the character variables in your dataset. Regex is overkill for such a simple test.
So if your existing dataset is name HAVE this data step will create a copy into a new dataset named WANT that has the character values modified in the way you want.
data want;
set have;
array _ch _character_;
do index=1 to dim(_ch);
if not index(_ch[index],'%') then _ch[index]=' ';
end;
drop index;
run;
If you want to only do it when the % is at the end then change the test to:
if not char(_ch[index],length(_ch[index])) = '%' then _ch[index]=' ';
This is could be handled using Excel's Find and Replace. ?
