Oracle Forms Developer – Form Builder Reference, Volume 1

NEXT_BLOCK built-in
Description
Navigates to the first navigable item in the next enterable block in the navigation sequence. By default,
the next block in the navigation sequence is the block with the next higher sequence number, as defined
by the order of blocks in the Object Navigator. However, the Next Navigation Block block property can
be set to specify a different block as the next block for navigation purposes.
If there is no enterable block with a higher sequence, NEXT_BLOCK navigates to the enterable block
with the lowest sequence number.
