Subject:      Adding leading zeroes to a variable

Hi,

I have variable i, and wish to convert it into variable APP.

i    APP
1    0001
2    0002
3    0003
4    0004
5    0005
6    0006
7    0007
8    0008
9    0009
10   0010
etc.

I don't suspect that i would get any higher than two digits. How would I do
this?

Also, i is generated by this code:


Data ppi.test1b (drop=sfint);
    set ppi.test1a;
      do i = 1 to sfint;
            output;
      end;
   run;

Thus, I suspect i to be numeric (am I correct?)

When I have variable APP I plan to concatenate it to variable EST to give
me variable ITE.

Thus:

ITE=EST||APP;


Is there a mismatch of variable type? (EST had observations which are
number/letter combinations, so presumably are character strings) If so, how
do I fix the mismatch?

Thanks!
