Data file maintenance

Constant	Type	Value	Comment
Create process	Longint	32768	When this option is passed, compacting will be asynchronous and you will need to manage the results using the callback method (see below). 4D will not display the progress bar (it is possible to do so using the callback method). The OK system variable is set to 1 if the process has been launched correctly and 0 in all other cases. When this option is not passed, the OK variable is set to 1 if the compacting takes place correctly and 0 otherwise.
Do not compact index	Longint	2
Do not create log file	Longint	16384	Generally, this command creates a log file in XML format (refer to the end of the command description). With this option, no log file will be created.

Verify All	Longint	16
Verify Indexes	Longint	8	This option checks the physical consistency of the indexes, without any link with the data. It signals invalid keys but does not permit you to detect duplicated keys (two indexes that point to the same record). This type of error can only be detected with the Verify All option.
