st: Changing characters and letters in all value labels

[maria t <majvardrup@hotmail.com>]

Hi statalist members,
 
I would like to remove certain letters and characters in all my value labels and replace them with other ones.
 
I have used the following program to change the letter "z" to "a" in all the variable labels, but I can't find out how to do the same for the value labels.
 
Foreach i of varlist_all {
 
local a: variable label `i'
 
local a: subinstr local a "z" "a"
 
label var `i' "a"
 
}
 
I would be very grateful if any of you could help me solve this.
 
Thanks,
