Editing large files

Using Auxiliary edit or In-place edit, you can edit large files, regardless of their size, without the need to first break them up into smaller subsets.

If you do not select Inplace edit on the editor entry panel and perform either of these actions:
  • You attempt to edit a QSAM data set or a VSAM ESDS or RRDS data set defined with the REUSE attribute but it is too large to fit into available memory,
  • You attempt to edit a QSAM data set or a VSAM ESDS or RRDS data set defined with the REUSE attribute, and you specify a start position or record limit
File Manager uses an auxiliary file in order to fulfill your request and issues progress messages periodically during the pre and post edit copy process.
