Retentive ANY pointer

My program needs a few ANY pointers that need to be built programatically. I can of course do this for an ANY pointer on the temp stack by using the L-addresses. But I would like it to be retentive so I don't need to rebuild it in the next block call.

Is there a good way to make these pointers retentive?

Hi K0ICHI,

Look at SFC22 - CREATE_DB function.

hi K0ICHI,

you need to use other memory-areas then the TEMP-area.

When you use a FB, you can use the static-area in the instance-DB.

hope this helps.

regards,

 Right, so how do I declare an ANY pointer in the STAT area? It's not in the list of available data types.

Hello Koichi;

You are right, you cannot use an ANY variale type in a STAT parameter of a FB, directly.

Maybe the following FAQ can provide suggestions on a bypass:

How do you parameterize blocks, which have "ANY"-type or "Pointer" type parameters?

 Hi Daniel

If there is a bypass, I'm not smart enough to see it. I like ANY's because they make the block interfaces nice and tidy, but unfortunately they're not as powerful as they could be. Can't pass them from block to another, OR make them retentive, without several lines of ugly code.
