The DFSORT ICETOOL is a data set reporting utility that provides a batch front-end for DFSORT. It is capable of performing complex sorting, copying, merging, reporting and analytical tasks using multiple data sets in a single job. It can be called from a program or executed directly in a batch job. ICETOOL provides a set of 'operators' that provides a wide variety of tasks.<br>This course shows how to effectively exploit the benefits offered by this utility.<br><br>This course is available 'on demand' (minimum 2 students) for public presentation and for one-company, on-site presentations.
