Primary index
Every primary index file must be initialized with a header record:
POS 1 - 8 blank POS 9 - 16 '00010101' POS 17 - 77 'b (binary zeros)
This is a sample of JCL that initializes the header record of a primary index file. It can be run separately or added to the job that creates the VSAM files.
