SYMPTOMS

In FoxPro 2.6a for Macintosh, the RLOCK()function fails after locking 220 records due to a limitation of Macintosh file sharing.

MORE INFORMATION

Steps to Reproduce Behavior

  1. Confirm that file sharing is enabled by clicking the Apple menu, choosing Control Panels, and then selecting Sharing Setup.

  2. Create and run the following program:

    SET STATUS ON USE SYS(2004)+"Tutorial:Customer.dbf" SHARED SET MULTILOCKS ON DO WHILE !EOF() AND RLOCK() 

          SKIP
