I want to find all the matches of a given pattern in a string but doing fuzzy (approximate) pattern matching. I want to allow small variations (1 or 2 positions substituted) in the match. I have tried String::approx module, but I do not know how to manage syntax

...
use String::approx 'amatch';
my $pattern = "JEJE";
my $string = "EJKJUJHJDJEJEJEDEJOJOJJJAHJHJSHJEFEJUJEJUJKIJS";
while (?=/$pattern/) {
...

How could I achieve that this 'while' allow 1 substitution from $pattern? That is that "JEFE", "JUJE","JEDE",... would be true matches.

Thanks a lot in advance. JR
