Copying Unix files to MVS Datasets
Read more: Copying Unix files to MVS DatasetsA common task in z/OS environments is moving data between the Unix file system and traditional MVS datasets. Here is how to do it using the OCOPY utility in a JCL batch job. As mentioned in the previous post, another sample. This one copies a z/OS unix file to an MVS dataset. Also using OCOPY.…
