Hi Everyone! I was working on this data that has two numeric data fields with leading zeros. I wanted to concatinate without dropping the leading zeros to create a unique key. Can you guys help me please? Field1=0001234 Field2=0005678 New Data Field will be: New_Field=00012340005678   I tried this, but keeps dropping the leading zeros from both data fields before it concatinates DATA want; SET have New_Field=((LEFT(Field1)) || (LEFT(Field2)); RUN;   Thanks Guys!
