true if BFS is providing a record count in the FMC argument, false if the call is not supported by the BFS
| Info |
|---|
| This call was designed specifically for RTP57, which stores a record count as part of the file header. If the BFS does not support the call, a status of false is returned. In this case, processes that require a record count should execute a READNEXT loop to return a true record count. |
Called by | BASIC+ Get.RecCount function, or a direct call |
