Free form SQL

I have applied (I think) the correct PTF's on my V5R3M0 270 and I am attempting to compile an SQLRPGLE source member that has free format SQL in it and it is acting like it doesn't know what to do with it.

The error is:

6161 exec sql ======> aaa *RNF5347 30 a 368388 An assignment operator is expected with the EVAL operation.

The actual code from the member is:

c/free
if Mode = 'I';
exec sql
insert into pasa408a
values(:ID,:ADate,:Line1,:Line2);
endif;

It throws the RNF5347 error just after the exec sql.

I have some similar code on another V5R3M0 machine that compiles so I think this machine must be missing some PTF's or perhaps they were applied delayed?

Can't remember the PTF numbers although I think I found them on this list (somewhere). How can I tell if the PTF's are applied (or waiting as delayed)? Or, is there some syntax issue?

Thanks,
