This paper is a mini-user guide for DFSORT’s versatile ICETOOL data objective is to show you how to use DFSORT’s ICETOOL to accomplish complex tasks. DFSORT is a powerful IBM utility used to copy, sort or merge datasets. SORTIN and SORTINnn DD statements are used to specify input datasets. SORTOUT and . Following Figure shows the Normal Layout of a ICETOOL job: // DFSMSG DD SYSOUT=* –> This is where the DFSORT messages.

The ones that occur only 1 time are not printed. We could any of the existing masks.

It gives best utilization of system resources and efficient operation in bit and bit address spaces. These utility programs need to be used with appropriate DD statements in a JCL in order to achieve the specified functionality.


Utility programs are pre-written programs, widely used in mainframes by system programmers and application developers to achieve day-to-day requirements, organising and maintaining data.
