Dear Dirk,
Without giving a look at your routines, one can only make guesses…
1. Have you included the USERDUMP in the input file with the correct settings? it seems yes…
2. Is the common (TRACKR) include in both mgdraw and comscw routines? By default, it is
Best regards, luigi

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'.
