st: Using if in list of r(...)

I have the following problem: I would like to have all names of value
labels starting with the same prefix "l". But some of the value labels
do have already a "l" as a prefix.

I generate the list of value labels ( r(names) )with 
label dir

But I have not found a way to select only those with
if substr("`val'",1,1) ~= "l" 

For all value labels it would look like:
foreach val in `r(names)' {
local i = "`val'" 
labelrename `i' l`i' 
}

But neither foreach, local nor labelrename allow for an if-option. Any
hints, ideas?

Thanks,


Marc
