Can I increase the buffer size for data areas to 13K even if the block size for all my Datacom areas is still 4K?

The first value in the MUF SYSIN DATAPOOL card (a.k.a.DATALN) defines the size of the buffers used for data areas access (data buffers).  


We are planning to increase the block size of all our user data areas. Currently all these areas have a block size set to 4K. Is there any problem increasing the DATALN value from 4K to 13K? 


No, there is no problem but a lot a storage is wasted, as each 13K block will contain only 4K of data.
