soundex returning numbers only, no leading character

[cklager44]

data one;
input bankname $1-20;
length bankname $20;
cards;
new york bank
new york bank.
NEW YORK bank
new york bnk
new yrk bank
ne york bank
neww york bank

ew york bank
new york mets
;
run;
data two;
set one;
where bankname=*'new york bank';
run;

data three;
set one;
where soundex(bankname)=soundex('new york bank');
run;

data four;
set one;
banks=soundex(bankname);
test=soundex('new york bank');
run;

Datasets two and three have no observations.  Dataset four looks like this:

new york bank, 562152, N62152

...

new york mets, 562532, N62152

I also tried it in a proc sql and had similar results. When I use =* or soundex on a variable, it does not output the leading character. When I use it on a constant, the output looks as I expect it to.  What am I doing wrong?  Thanks

Show your LOG. Copy from the log and paste into a text box.

For set Two I get:

Obs	bankname
1	new york bank
2	new york bank.
3	NEW YORK bank
4	new york bnk
5	new yrk bank
6	ne york bank
7	neww york bank
8	nnew york bank

For three:

Obs	bankname
1	new york bank
2	new york bank.
3	NEW YORK bank
4	new york bnk
5	new yrk bank
6	ne york bank
7	neww york bank
8	nnew york bank

And for Four:

Obs	bankname	banks	test
1	new york bank	N62152	N62152
2	new york bank.	N62152	N62152
3	NEW YORK bank	N62152	N62152
4	new york bnk	N62152	N62152
5	new yrk bank	N62152	N62152
6	ne york bank	N62152	N62152
7	neww york bank	N62152	N62152
8	nnew york bank	N62152	N62152
9	ew york bank	E62152	N62152
10	new york mets	N62532	N62152

Slightly different code (this includes the proc sql example I mentioned), but it gets the point across.
