specifies the number of pages that are allocated
for a file.
The ALQMULT= data set option is related
to the ALQ= data set option. With the ALQ= data set option, you specify a
block value that is preallocated. With the ALQMULT= data
set option, enough blocks are preallocated to accommodate the number of pages
that you specify. With the ALQMULT= data
set option you don't need to know how big the page size (buffer size) is for
a file or to determine how many blocks are needed for the number of
pages.
