Hi All,
In a JCL,i gave spaces as 'SPACE=(CYL,(20,5),RLSE)' and my record length is 105.Can any one tell me how many cylinders it will take maximum and maximum how many records i can store in this dataset?
Regards,
Bipin Peter

In theory - because fragmentation can play havoc with these sort of calculations.

Integer (27998 / 105) = records per block
2 * records per block = records per track

Theoretical maximum space allocated = 20 + (15 * 5) cylinders
