# ADSKeyCount()

Retrieve the number of keys in a specified index

Syntax

  ADSKeyCount([<xTag>], <cIgnoredIndexFile>, [<nFilterOption>]) --> nKeyCount

Arguments

  <xTag> Numeric order number OR index tag name. Default is current index.
  <cIgnoredIndexFile> This parameter is not processed. In other Harbour RDDs, the second parameter to "ordKeyCount" takes a second argument to identify a particular Index File in cases where two files are open that contain orders with the same name. The ADS driver does not support this and will select the first order with the requested name. To stay consistent with other RDDs, therefore(),the second parameter is reserved and the <nFilterOption> is passed as a third parameter.
  <nFilterOption> Indicates if filters and/or scopes are to be respected if set.
  Options are defined in ads.ch:

ADS_RESPECTFILTERS | Respect filters and scopes
ADS_IGNOREFILTERS | Ignore filters and scopes
ADS_RESPECTSCOPES | Respect scopes only

Returns

  <nKeyCount> The number of keys within the current index.
