Based on your suggestions and information in the FLUKA advanced course I made an attempt to use latching to separate the Bremsstrahlung dose by flagging all particles created in a bremsstrahlung event and using that flag for scoring by adding
To the mgdraw.f, USRDRAW entry:
IF ( ICODE .EQ. 208) THEN
ISPUSR(1) = 1
END IF
To comscw.f:
COMSCW = ZEROZERO
IF (ISPUSR(1) .EQ. 1) THEN
COMSCW = ONEONE
END IF
After testing, I know that USRDRAW is flagging ISPUSR(1) when there is a bremsstrahlung event but when comscw.f runs, it shows ISPUSR(1) = 0. It is like the values I set with mgdraw.f are not being propagated. From my understanding, propagation of ISPUSR values should happen by default but I added the default stupre.f routine to be sure and ISPUSR values are still not propagating. All my user files compile without error and the simulation runs fine. Am I missing something that allows the ISPUSR values to be propagated?

This is in the FLUKA advanced courses, under 'user routines'.
