Topic: Image Copy Extract utility

Change description: Important note added. (Please note: "[TABLE]" in the excerpt below stands in place of the table which exists in the actual documentation.)

Image Copy Extract utility

The Image Copy Extract utility extracts specified segments from an IMS™ image copy data set to produce QSAM data sets and to customize the QSAM output.

The Image Copy Extract utility does two things:

  • It produces a variable-blocked QSAM data set from an IMS image copy data set.

Only QSAM data sets can be used as input to IMS HD Compression Extended functions.
  • It customizes the output QSAM data set so that it contains only the segments that you want to extract.
The Image Copy Extract utility extracts segment data. To access the Image Copy Extract utility, you can use several of the IMS HD Compression Extended functions. The following table lists the functions that can access the Image Copy Extract utility.
