add a 0 within the character

[simonqin]

Hi,

I am working on the health dataset and try to add a '0' value within all the ID number.

such as 

original ID      New ID

110011001     1100110001

110012001     1100120001

......

I want to know whether it has a syntax regarding to this.

[Ksharp]

data have;
length x $ 20;
x='110011001';
y=substr(x,1,6)||'0'||substr(x,7);
run;
