Create physical copy and logical copy

The Create Image Copy function supports two process types; physical copy and logical copy.

Physical copy creates new data sets without changing the compression routine of the input image copy data set. Logical copy creates new data sets by using a different compression routine from the input image copy data set. Logical copy can also create new image copy data sets by converting the format of the input image copy data sets.

Use the CRCTYPE keyword of the ICEIN control statement to specify whether to apply physical copy or logical copy.
