UBOUND on empty array is -1, Ok to use this ?

[Peter Noren]

UBOUND on empty array return -1
Is it safe to use this value to test that array is empty ?
Is there a better/safer way ?

$COMPILE EXE

FUNCTION PBMAIN () EXPORT AS LONG
DIM gsXarr() AS GLOBAL STRING

MSGBOX STR$(UBOUND(gsXArr)) 'Return -1
END FUNCTION

Thanks for your help!
