Output Block Properties dialog box

General tab

Settings
Spacing	Before – Spacing (in millimeters) above the block. After – Spacing (in millimeters) below the block. Line – Fixed block height (in millimeters). To enable this option, you must select Use line. Note: By selecting Use line you disable the page break modes Break between fields and Break between lines in fields. Keep lines together – If the frame is not big enough for the block and its associated free blocks, the blocks are moved to the next page. This setting is ignored if the frame on the next page is too small. Only applicable if Frame Overflow is set to Default, and when using a StreamIN or XMLIN event with parent blocks. The child blocks inherit this setting from the parent block.
Indentation	Top – Top indentation (in millimeters, counted downwards using a negative value) of the block. Left – Left indentation (in millimeters) of the block.
Free blocks	Enter the names of the free blocks you want to add. Before first instance – Add a free block before the first instance of this block. After last instance – Add a free block after the last instance of this block. Before overflow – Add a free block at the bottom of the frame, on the current page, before a page break. After overflow – Add a free block at the top of the frame, on the following page, after a page break. After block children – Add a free block after the last instance of any block children. If the block has no children, the free block will be invoked after each instance of the main block.
Sort	Use sort keys to specify the order in which block data is added to the output, see Sorting.

Frame Overflow tab

Settings
Default	Move the block, and all associated free blocks, to the next page after a page break. Note: Not applicable if it is the first block in the frame.
Break between blocks	Similar to the Default option. The difference is that the page break can separate blocks and free blocks.
Break between fields	The page break can occur between fields in blocks and free blocks. If the block has Use line enabled, this mode will behave like the Break between blocks mode.
Break between lines in fields	The page break can occur between lines within a field. This mode will not work if the field is rotated. If the block has Use line enabled, this mode will behave like the Break between blocks mode.
