Ken: >>> Look at the Memory Manager chapter in Inside Mac Vol. I for details about the block header. I think Vol. VI has more info about how these data structures were changed for System 7 <<< No. Inside Mac completely omits 32-bit Memory Mgr data structures. I'm sure that was done deliberately to prevent programmers from depending on them. They could conceivably change again. Block headers in 32-bit mode have a very similar structure as in 24-bit mode, but they are 12 bytes instead of 8. Steve
