Sorry, the message got cut off. To continue:

FUNC newid()
LOCAL nOldSel,cAlias,nNewKey,cOldReprocess
nOldSel=SELECT()
cAlias=ALIAS()
cOldReprocess=SET("REPROCESS")
SET REPROCESS TO AUTOMATIC
IF !USED(mydatabase!identity)
USE mydatabase!identity IN 0
ENDIF
SELECT identity
IF SEEK(UPPER(cAlias), "identity", "TABLENAME")
IF RLOCK()
nNewKey=identity.keyvalue
REPLACE identity.keyvalue WITH identity.keyvalue+1
UNLOCK
ELSE
nNewKey=-1
ENDIF
ELSE
nNewKey=-1
ENDIF
SELECT (lnOldArea)
SET REPROCESS TO lcOldReprocess
RETURN nNewKey
ENDFUNC

The error trapping isn't very sharp in this example, but you'll get the idea.
Of course, an index on TABLENAME is required for table IDENTITY.
