Ah ha! I'd gone around in circles trying to work out what combination of actions resulted in that error. Thanks!The 2.24 DFS dissassembly (by Greg Cook) mentions a 'execute privilege' bit which is repurposed from bit 0 of the 1770/2 command and if a deleted data address mark is encountered during a read and this bit is set it'll happily continue else it'll report a 'Execute Only' message. (See around L9410).
