Qualified Data Structure with SQL Insert

I thought I was being clever...perhaps not...I can't get the variables in
the INSERT clause right. I've tried using pIn_SQLCA subfields or In_SQLCA
subfields and I get the :In_SQLCA.SQLWRN -> SQL0312: Position 21 Variable
IN_SQLCA not defined or not usable as well as the other side SQL0312:
Position 30 Variable SQLWRN not defined or not usable. Why can't I do this?

In_SQLCA = pIn_SQLCA;

Exec SQL
Insert Into WEBSVC/WSVLOGP (WSV_SQLCAID,
WSV_SQLCABC,

Return 1;
