How we found and calculate the F1CREDT for Object O02025 in DTOC4SYS ?
Mapping the OBJECT=DTOC4SYS we obtain
VOLSEQNO DS BL2 +74
DS1CCRED DS XL3 +76
CREDT DS XL3 +76 Create Date
F1CREDT DS XL3 +76 Create Date
DS1CEXPD DS XL3 +79 Expiration Date
F1EXPDT DS XL3 +79 Expiration Date
DS1EXPDT DS XL3 +79 Expiration Date
So at the +76 we get the F1CREDT - create date - which is in the following format:
DJDB -- Date in Julian Discontinuous Binary format
FL3; i.e., FL1'YY',FL2'DDD'
YY is the number of years since 1900.
DDD is the day within the year.
Dates within the VTOC are in DJDB format.
Max valid date in this format is yr 2155 day 365 (x'FF016D')
Invalid date will contain yr 2155 day 999 (x'FF03E7')
