A utility work data set is allocated as follows:
  • Primary space, in 4K blocks, equals: 
    2 ((((x + y)b)/4096)+2)
    x =
    the number of records in the existing data set
    y =
    the additional number of records to be added to the data set. This number is variable and depends on the user specifications on a MOVE or COPY subcommand. The value may be 0.
    b =
    the number of bytes (characters) per record
  • Secondary space equals: 
    Primary space/2
