MERGE, Output File Qualifiers, /ALLOCATION
 *Conan The Librarian 

    Specifies the number of blocks to be preallocated for the output
    file. Used for optimization when you know that the output file
    allocation will differ substantially from the total input
    file allocation (because you are reformatting data or omitting
    records).

    Format

      output-file-spec/ALLOCATION=n
