Par2: Incremental locator delay 2001-11-16 -- Kevin Erskine This is a template solution -- letting CW do what it wants....
Generated Code.... Blue code is standard CW generated code..
BRW1::Sort0:Locator.TakeKey PROCEDURE
ReturnValue BYTE,AUTO
!--- ! (BGN) Incremental Locator Delay
!---
!--- In order to reduce file I/O for Incremental locators, take the keycode and
!--- if there are more in the buffer continue until no more
!---
DelayUntilTime LONG(0) ! Delay Field
eStdDelayTime EQUATE(35) ! 35/100 of a second
!---
CODE
!---
LOOP ! Loop until no KeyCodes in Buffer
!-
ReturnValue = PARENT.TakeKey()
!-
DelayUntilTime = CLOCK() + eStdDelayTime ! Set Delay Time
LOOP WHILE NOT KEYBOARD() | ! Pause Until A KeyCode
AND ABS(CLOCK() - DelayUntilTime) <= eStdDelayTime ! OR TimeOut
YIELD() ! Give other Processes time
END
!-
IF KEYBOARD() ! Is there another KeyCode
ASK ! Get Next KeyCode
CYCLE ! Process KeyCode
ELSE
BREAK ! All Done
END
!-
END
!--- ! (END) Incremental Locator Delay
RETURN ReturnValue
