From the PBP 2.60 manual:



DEFINE WRITE_INT 1 ‘Disable/Enable INTs in WRITE



If you put this in your DEFINE block, it will turn off your INTs before the WRITE and enable them after the WRITE.

Note that if you include this DEFINE, it will always ENABLE ints when the write is finished, whether or not they were enabled when the WRITE was invoked.
