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.

This will copy records from 1 to 99 and then the last record. Prints the number of records with value greater than Usually used to manage VSAM datasets.
A few of them are listed below with their functionality:. It gives best utilization of system resources and efficient operation in bit and bit address spaces.
Frequently used sort tricks using these utilities are explained in the next chapter.
JCL – Utility Programs
That is the values that appear only once. List indicates the output dataset.
For example, a file containing names of employees can be split into 26 files, each containing the names starting with A, B, C and so on.

A File can be split into n files based on a specified condition. Posted by cobolbasics at See the Use of Edit patterns.
These utility programs need to be used with appropriate DD statements in a JCL in order to achieve the specified functionality.
