reading char by char in a string

That is not the same question that you put in your Subject header.
Please be a bit more precise in wording your questions.
I don't know which one to answer...
reading char by char in a string
perldoc -f sysread
(but nobody really wants to do this, it will be slow)
_processing_ char by char in a string
foreach ( split //, $string ) {
# do something with char in $_
}

So there should be two "matches"
moreinfo
evenmoreinfo
since someinfo is NOT between underscores?

Though split(), as pointed out in another followup, will do the
job with the particular problem you presented, you can do it
with a regex too.
perldoc perlre
perldoc perlop
-----------------------------
#!/usr/bin/perl -w
use strict;
$_ = 'someinfo_moreinfo_evenmoreinfo_';
#while ( /_([^_]*)(?=_)/g ) { # same thing, all on one line
while ( /_ # underscore
( # start remembering matched chars in $1
[^_]* # zero or more of anything except underscore
) # stop remembering matched chars
(?=_) # see if the next char is underscore, without
# counting it in this match (because we
# need it at the beginning of the _next_ match)
/gx ) {
print "$1\n"; # do something with the matched chars in $1
