Hi everyone:

On my new work I have to go back to many concepts that I used in the past and calculations and I do not remember many things.

Right now I am trying to create PO data set. And I would like to know if any body up there knows. How can I calculate the space?

If I am using cylinders, tracks, or blocks. Please let me know if there an equation to calculate the right space that I will used in a dasd :

HI Veena

Can you please upload the excell spreadsheet to the forum. Maybe other people can use it too. The TSO command looks like a clist and if it is, it will not be readily available in all IT shops.

Please send me the spreadsheet to calculate the space. You know that the person that comes from the PC world we always managed ourself with MB or GB. So I just want to go from MB or GB to tracks or Cylinders.

Example I would like to have 10MB of space to a dataset. So how much is that in cylinders or tracks. The same thing if I want 10GB of space. So it is a conversion formula that I want.

Also you can add any attachment on this forum. So if you have anything please send me the information I need it to calculate the exact amount of space that I would use in my datasets.

I used at the command line dasdcalc and it did not work. I do not why. But if you have the formula as I describe above please send it to me.

I believe TSO DASDCALC is a shop dependant. The xls you've provided here is quite useful............
