; Change History (most recent first):
;
; <10> 7/1/92 DCL This file is the replacement for the now obsolete
; QDOffscreenEqu.a. Changed the 'including' name to match the new
; file name.
; <9> 6/14/91 JL Checked in official MPW 3.2ƒ version. Adjusted keepLocalBit's
; comment; removed <27MAR90 KON>.
; <8> 1/30/91 gbm sab, #38: Change the already including this file variable to
; all uppercase (for security reasons)
; <7> 1/15/91 KON Change useMFTempBit to UseTempMemBit. [csd]
; <5> 3/27/90 KON Add KeepLocal flag (bit3) for gWorld flags.
; <2> 12/28/89 dba add equates for MF temp. memory bit
