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.

Is for formatting purpose. It is usually used to create empty dataset or delete an existing dataset. This giving us a sample records for testing. Above shows the unique values in the column 5,8,ZD.

Icetkol by cobolbasics at Utility programs tutoril pre-written programs, widely used in mainframes by system programmers and application developers to achieve day-to-day requirements, organising and maintaining data.
ON indicates the column for which unique must be found. BLANK replaces all the leading zeros. Note the format is decided as follows: List indicates the output dataset.
Only the header and trailer kept in place and rest of the data is sorted. It gives best utilization of system resources and efficient operation in bit and bit address spaces.
Matthew McKenzie 8 August at Usually used to manage VSAM datasets. Ashwani Sharma 24 November at The string within is also printed before the value is printed. This displays the count of records having field 36,2,ZD greater than These utility programs need to be used with appropriate DD statements in a JCL in order to achieve the specified functionality. Numeric fields with usage COMP: Also note that both the titles are printed.
Raj icetlol Bhakthavachalam 4 September at The ones that occur only 1 time are not printed. Input and output datasets can be defined using user defined DD names.
