Three variables are input in the CG Title card: IVLFLG, IDBG, TITLE. The format is (2I5,10X,A60). The first integer value (IVLFLG = Input VoLume FLaG) is a flag to indicate how to normalise the quantities scored in regions by the FLUKA option SCORE: IVLFLG = 0 means that no normalisation must be performed (output values are total stars or total energy deposited in each region). IVLFLG = 1 and IVLFLG = 2 are reserved for future use and they have currently no meaning in FLUKA. IVLFLG = 3 means that the scores must be normalised dividing by region volumes input by the user just before the GEOEND card. The second integer value can be used to modify the format with which body and region data are read: IDBG = 0 or 10 : default fixed format for both bodies and regions = -10 : high-accuracy fixed format for bodies; default fixed region format = -100 : high-accuracy fixed format for bodies; region fixed format allowing more than 10000 regions = 100 : default fixed format for bodies; region fixed format allowing more than 10000 regions Note however that the maximum number of regions is dimensioned to 10000 in INCLUDE file (DIMPAR). Any other IDBG value should be avoided. The value of IDBG is irrelevant if free geometry format has been requested (see the GLOBAL command). The remaining 60 characters can be used for any alphanumeric string at the user's choice. If fixed format is not used, the value of IDBG is irrelevant.
