I forgot to answer your second question:

I guess you mean if you have printed them on the same logical output unit.
Suppose you have two EVENTBIN detectors:
1st record: RUNTIT, RUNTIM (1st detector)
2nd record: RUNTIT, RUNTIM (2nd detector)
3rd record: NB,TITUSB(NB),JTUHLP,IDUSBN(NB),SNGL(XLOW(NB)),SNGL(XHIGH(NB)),
NXBIN(NB),SNGL(DXUSBN(NB)),SNGL(YLOW(NB)),SNGL(YHIGH(NB)),
NYBIN(NB),SNGL(DYUSBN(NB)),SNGL(ZLOW(NB)),SNGL(ZHIGH(NB)),
NZBIN(NB),SNGL(DZUSBN(NB)),LNTZER(NB),SNGL(BKUSBN(NB)),
SNGL(B2USBN(NB)),SNGL(TCUSBN(NB)) (1st detector)
4th record: NB,TITUSB(NB),JTUHLP,IDUSBN(NB),SNGL(XLOW(NB)),SNGL(XHIGH(NB)),
NXBIN(NB),SNGL(DXUSBN(NB)),SNGL(YLOW(NB)),SNGL(YHIGH(NB)),
NYBIN(NB),SNGL(DYUSBN(NB)),SNGL(ZLOW(NB)),SNGL(ZHIGH(NB)),
NZBIN(NB),SNGL(DZUSBN(NB)),LNTZER(NB),SNGL(BKUSBN(NB)),
SNGL(B2USBN(NB)),SNGL(TCUSBN(NB)) (2nd detector)
5th record: NB, NCASE, SNGL(WEIGHT) (1st detector)
6th record: NB, NCASE, SNGL(WEIGHT) (2nd detector)
7th record: binning data 1st event (1st detector)
8th record: binning data 1st event (2nd detector)
9th record: NB, NCASE, SNGL(WEIGHT) (1st detector)
10th record: NB, NCASE, SNGL(WEIGHT) (2nd detector)
11th record: binning data 2nd event (1st detector)
12th record: binning data 2nd event (2nd detector)
...etc
However, I don't think it is a good idea to direct all the outputs to the same
file. It is easy to write a program which reads alternatively from 2 or more
files. But if having only one file is so important for you (why?), you can
print the output of each detector to different files, and then concatenate them
into a single file using the cat command. Results referring to the same event
can be easily connected, since they have the same value of NCASE.
