[no parameter]
|
If no parameter is specified, PTC ALD will deactivate the alignment process from the current point onwards, in the given stream. When this form of syntax is used, it must be the last alignment property in the stream.
|
||||
x or X
|
Tells PTC ALD to wait until formatting of all aligned streams has been completed on the page before processing the current stream. When this form of syntax is used, it must be the unique alignment property in the stream.
For example if you are using this command to align text in multiple columns/streams which each have running header references, you would use this parameter in your running header frame text stream. PTC ALD will wait until the whole page has been formatted before evaluating the appropriate running header text.

id
|
Alignment name label whose presence indicates the start of a block that is to be aligned with other blocks from other streams. PTC ALD will automatically sync or re-sync the start position of all aligned blocks across streams, based on the alphanumeric position of their labels. Labels can be any name or number, but must be sequential within each formatted stream.
|
||||
top
|
Specifies how to align text in different text streams.
|
||||
sets_down
|
Specifies whether the alignment block can flow along other sets. The given value is the sum of the given binary numbers of all permitted sets (for instance, 7 would allow the current block to flow along sets 1, 2 and 4).
|
||||
sets
|
Specifies to which alignment block sets the current block belongs. PTC ALD will align together all blocks belonging to common sets. The given value is the sum of the given binary numbers of all permitted sets (for instance, 7 would align the current block with sets 1, 2 and 4).
|
||||
sets_bottom
|
Specifies which alignment block sets will be pushed down to the bottom of the current block, i.e. which block sets will have their vertical start position impacted by the current block depth. The given value is the sum of the given binary numbers of all permitted sets (for instance, 7 would push sets 1, 2 and 4 to the bottom of the current block).

In a complex SGML/XML composition, you may use <?queue> to ensure a correct processing order of all paragraph properties.

|
In a complex SGML/XML composition, it is very likely that you will need to generate the property dynamically (using a showstring, see <?show> for further information), extracting the label and alignment set information from data context.
