I have a DB composed by many arrays. When I use the function (read or write DB) I can not assigne the entire DB in the SCRBLK or DSTBLOCK, only a single array. Do I'm making a mistake? There is any other set up? [snip] ... thanks in advance

Due the small size of the ritentive memory I have to use this function and is not so nice to copy every single array or to create a big array that include all the data. many thanks in advance.

TIP: pay attention to doesn't save data to SD too frequently, because it could lead to premature end of live of it.
