[comp.sys.mac] Retrace Tasks in LSP

rs4u#@ANDREW.CMU.EDU.UUCP (05/06/87)

I have done simple retrace tasks (flashing the menu bar at half-second
intervals, etc) in Lightspeed Pascal. Generally, Lightspeed Pasal
preserves the necessary registers.

I'll dig out the code from my archives and post it.
