RE: ALWNULL(*USRCTL) v ALWNULL(*YES) was (strange SQL dumps)

Frank,
        There is no reason to have ALWNULL() in your program unless you
coded a file in the F-specs that allows nulls.  ALWNULL() have no effect on
any embedded SQL.  By the way I do not see in (V5.1) RPG manual anything
about ALWNULL(*YES).  Could that be your problem?   *USRCTL means you test
and set on/off the null indicator used for Input/Output.  The other useful
option is *INPUTONLY allows testing of the null indicator but nothing else.
See page 203-209 in V5.1 RPG reference. 

Thank you,

Thanks Carel,
I still dont understand what is the difference between
ALWNULL(*USRCTL) and  ALWNULL(*YES).
I thought  (*USRCTL)  did everything (*YES) did and
more (dont know what more).

Anyone shed light on this, and does the precompiler
treat the ALWNULL parm differently to the RPG compiler.

Frank,

ALWNULL(*USRCTL) gives you the possibility to use the %NULL bif.

I could not use that option, because my programmes run in batch and can
accept any kind of prepared SQL statement.

It is more a problem with the compilation, not the well-honoured and
all-loved precompiler (which appears to be older than RPG II).

Regards,
Carel Teijgeler.
