Before I start my question, let me provide an example
How much total space be allowed for SPACE=(TRK,(10,5))
I read somewhere during my training that the total units can be calculated by using the following formula
Total units(Trks/blks/cyl)= Primary + 15 * Secondary.
Thus as per this formula
SPACE=(TRK,(10,5)) should occupy 85 Tracks
My question here is that whether the formula that I used is correct or not?
and if it is correct, why do we use a factor 15 to multiply to the secondary
