remove the first leading zero from charc variable

[Bal23]

I need to remove the first zero, some obs have values like 00234, 00a234, and i only need to remove the first zero

can anybody advice how to get rid of the first "o" but not all leading zeros? Thanks

v2= substr(v1,verify(v1,'0'));

You don't say if you want to remove 0 if there is only one leading zero. If that is the case then one way is

if index(v1,'0')=1 then v2= substr(v1,2);

if ony replace the first zero when you have 2 leading zeroes or more then

if index(v1,'00')=1 then v2= substr(v1,2);
