BUG: FERROR() Returns 5 When File Handles Exhausted

• Microsoft FoxPro for Windows, version 2.6a

SYMPTOMS

The FERROR() function returns 5 when a file cannot be created because no file handles are available. The FERROR() function should return 4 when a file cannot be created due to insufficient file handles.

RESOLUTION

Instead of checking for a return value of 4, check for a return value of 5. The error 5 should mean Access Denied.

STATUS

Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
