Two columns into one

[mmagnuson]

Hello,

I have a variable of ID numbers (0001) and there needs to be an A before all of the numbers

i.e. I have a variable ID: 0001  and I want it to be A0001.  There needs to be an A before all of the numbers in the column

I'm sure it's an easy thing but I can't figure it out!

Please help!!

Thanks

Concatenate -->cats('A',your_variable)

If your variable is already defined as $ 4, you will need to expand the length to hold an additional character.  For example:

data want;

length ID $ 5;

set have;

id = 'A' || id;

run;
