regexp_replace with very large variables

Folks:

I'm trying to write a procedure that uses the regexp_replace SQL function with very large variables.

The variables are 256000 characters long.

exec sql set :newvar = regexp_replace(:oldvar, regex, replacement, 1, 'i');

If I just define the variables as char (256000), the compile fails with a SQL0312.

Is the right approach to define the variables as SQLTYPE(CLOB:256000) and do a ...

oldvar_DATA = somevalue;
oldvar_LEN = %len(%trim(somevalue));

... before invoking the SQL function?

Thanks!

david
