1 in stead of 13 was a typo. SET RANT ON and SET RANT off means that whatever is between those two lines are ment not to be taken too seriously, but more like a friendly joke.

>>SET EXCLUSIVE ON & Not OFF, OFF is if you must share, to pack it must be ON!!!!!!!!!

>>By the way, SET EXCLUSIVE OFF is usually only set ONCE in your program, or in the config.fpw file. In stead you add the EXCLUSIVE keyboard whenever you need it

>>And if you need to PACK regularly, you should reconsider your design. PACK should typically be used about once a year to clean up the tables, not daily or weekly!
