Is there some simple formula that a person can use to know how many blocks, or tracks, or cylinders one should allocate when creating a dataset when I know how many bytes, kilobytes, gigabytes, etc. a file on my PC is that I will be uploading to my mainframe? If someone could allocate a file in Blocks or Tracks when would I want to choose one or the other. I don't know when someone wants to use one or the other. Due to lack of knowledge I seemed to always allocate way to much space and it would be nice to just have a basic formula or some little Java program that I could plug the amount of bytes I have to know how many tracks, or blocks I would need to allocate to hold it.
Thank you in advance for your help,
