The bit 7 (left most bit) of parameter 912 enables the Macro Executor routines. Setting that to 0 should turn off the conversational screen that shows up in edit. My info shows that this is effective with the firmware version 0463.
Caution!! I have not personally done this to a 0 series control and none of my documentation says what all may happen if you set this to 0. Some configuration parameter change will require controller initialization to become effective. There is a note that says that the part program storage size is slightly reduced when 912 bit 7 is activated. IME, any time I have seen that type message it means that the program memory will be initialized. Setting it back to 0 will likely require program memory to be initialized too. Prior to doing any changes to configuration parameters you need to make a complete backup of all the CNC parameters, PMC parameters, Pitch comp values, and any other data you wish to keep (programs, tool offsets, fixture offsets).
As a side note, the list price on the software and hardware to program the order made macro cassette with a PC was about $10k in 1996.
