Calculating CV capacity for mainframe systems
When creating a CV, you can specify the CV's capacity. However, there is a margin of error between
the user-specified CV capacity and the actual CV capacity. To estimate the actual CV capacity, use
the following formula. The resulting CV capacity is expressed in megabytes.
