Re: remove the first leading zero from charc variable

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);
