TRACKS specifies ranges of tracks to be printed.
c1,h1
Specifies the cylinder and head number of the beginning of the range. Specify hexadecimal numbers as X'c1' or X'h1'.
c2,h2
Specifies the cylinder and head number of the end of the range. Specify hexadecimal numbers as X'c2' or X'h2'. The c2 must be greater than or equal to c1. If c2 equals c1, h2 must be greater than or equal to h1.

You can enter X'FFFFFFF' (or 268435455) as the high cylinder value. This causes DFSMSdss to choose the high cylinder value to be the end of the volume.

DFSMSdss verifies that the range is within the limits of the device. If you do not specify all four values for a range, DFSMSdss provides the missing values unless the omitted value causes a syntax error. No intervening values can be omitted. For example:
