parse error when calling function in plpgsql

I have a function that returns a record that works fine when I call it from psql:

mydb=# select * from myfunc(...params...) as (col1 real,col2 integer);
col1 | col2
---------+----------
0.806667 | 17000104
(1 row)

I have tried to call it from within another function like this:

...
declare
myrec record;
...
select * into myrec from myfunc(...params...) as (col1 real,col2 integer);
...

but I keep getting a parse error:

WARNING: Error occurred while executing PL/pgSQL function myparentfunc
WARNING: line 27 at select into variables
ERROR: parser: parse error at or near "$1" at character 72

How do I get the record returned from myfunc to be assigned to myrec?

Thanks,
David Witham
