If you've got a few hundred thousand records in the table, ZAP would be

quite a bit faster.

Heck, I'd be tempted to do my own ZAP routine before going the DELETE ALL /

PACK route...

Function myzap

parameter cTbl2Zap

LOCAL cDataDir

cDataDir = addbs(justpath(dbc()))

select (cTbl2Zap)

copy structure to (cDataDir + cTbl2Zap + "_tmpthing") database (dbc()) with CDX

DROP TABLE (cTbl2Zap)

USE (cTbl2Zap + "_tmpthing")

copy structure to (cDataDir + cTbl2Zap) database (dbc()) with cdx

drop table (cTbl2Zap + "_tmpthing")

use (cTbl2Zap)

return

Of course, if ZAP was hitting an error, maybe the DROP TABLE would have

triggered the same thing....?
