VERW Verify Write (286/386) Flags: O D I T S Z A P C
*
VERW Source
Logic: if source can be written to then ZF . 1
else ZF . 0
This instruction sets the zero flag if the current procedure can use
source as a selector to write to. If the zero flag is not set,
writing to source will cause a memory fault.
