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.

Used to return control to user icftool terminate. It is usually used to create empty dataset or delete an existing dataset. These utility programs need to be used with appropriate DD statements in a JCL in order to achieve the specified functionality. Note that only the column we mentioned in ON is printed in the report. Prints the number of records with value greater than Also note that in the above figure the title is being printed every page.

Also note that both the titles are printed. BLANK replaces all the leading zeros.

List indicates the output dataset. Following can be used to remove duplicates from a file and save it to another file. ON indicates the column for which unique must be found. Usually, this is not recommended icerool view of performance for large files.

Input and output datasets can be defined using user defined DD names.

This will copy records from 1 to 99 and then the last record. We can turn off that display using NOCC. The ones that occur only 1 time are not printed. The string within is also printed before the value is printed.

Is for formatting purpose.
