TRKs and CYLs? Most of our allocations are in MEGs. Doesn't everyone do that
these days?
SPACE=(1,(5,1),RLSE),AVGREC=M Allocate in MEGs
I would have thought allocations in records or thousands of records,
or millions of records, e.g.:
SPACE=(440,(100,5),RLSE),AVGREG=M
allocate space for 100 million records of 440 bytes long.
Folks responsible for an application usually have some rough idea
of the number of records (right?) and they know the size of the
records. Records relate to something concrete (customers,
inventory, employees, etc.) whereas megabytes is more abstract.
But, hey, I live in the ivory tower.
