hi there
the sequnce with alpha _ _ is valid but not _ _ _



I replaced the 4 four lines in your program with the following four lines.
 
next if ( $char !~ /[a-z]/i );
my $char2 = substr $_, $ii+1, 1;
next if ( $char2 !~ /[a-z ]/i );
my $char3 = substr $_, $ii+2, 1;
next if ( $char3 !~ /[a-z ]/i );

 
Changed the input to
 
$_ = ' hello. how  a,re you hel?lo ';
 
Output:
$\%hash = {
'e y' => 1,
'ell' => 1,
'hel' => 2,
'how' => 1,
'llo' => 1,
'lo ' => 1,
'ou ' => 1,
'ow ' => 1,
're ' => 1,
'u h' => 1,
'w  ' => 1,
'you' => 1
};
 
Wags ;)
