NVL2 in pro cobol giving the error.

Question

For some reason we are getting an compiler error when we use NVL2 function in embedded sql statement in a pro-cobol module. Here is the output from the compiler. Do we have to add any options to recognize the new functions/keywords?
procob iname=vas107h2.pco include=/oracle/home/product/9.2.0/precomp/public ireclen=132 oreclen=132 sqlcheck=full ltype=none

I'm not familiar with Pro*Cobol, but there's a similar issue with Pro*C, the parser does not recognize this built-in function. Given workaround is:
1) Use NVL() instead of NVL2().
2) Use Dynamic Sql in Pro*C. For example:
EXEC SQL EXECUTE
declare
v_var varchar2(100);
BEGIN
execute immediate 'select nvl2(user, user, 'N/A') from dual' into v_var;
END;
END-EXEC;
If that doesn't help, you should contact Oracle support.
