ON FILL BUFFER block

The ON FILL BUFFER block is used to fill a page of rows into the dynamic array, according to an offset and a number of rows.

This data block is used in the DISPLAY ARRAY blocks.

The offset can be retrieved with the FGL_DIALOG_GETBUFFERSTART() built-in function and the number of rows to provide is defined by the FGL_DIALOG_GETBUFFERLENGTH() built-in function.
