Specifying your processing options
Once you have your list of data sets or members built up, you can specify the processing options that you would like to use when performing your find or change operations.
Choose among the following options:
- JCL source format
- Select this option when your data set contains JCL and you want
that JCL syntax to be preserved when making changes. The following JCL statements are supported:
- DD
- EXEC
- JCLLIB
- JOB
- OUTPUT
- PROC
- SET
- XMIT
All other statement types are treated as data records.
When File Manager recognizes one of the supported statement types, it attempts to process the CHANGE command in such a way as to preserve the JCL syntax. For the eligible JCL statements, changes in a record that would result in the text being longer than 255 characters before reformatting (due to the new string being longer than the old string) within a JCL statement, are not made.
The file must be non-VSAM and have a fixed record length of 80.
- Use REXX proc
- You can use this option to specify a REXX procedure that manipulates your records in more complex ways than by issuing FIND and CHANGE commands within the panel.
- REXX no update
- Select this option when your REXX procedure performs no updates to the FCH data set. If selected, it forces the allocation of the data set as input only. All updates to the data are ignored.
- Use I/O exit
- Select this option when you want to specify a user I/O exit for compressed or encrypted data sets.
- Immediate change
- Select this option when you intend to use the CHANGE command, but want the input data set to be updated immediately (without displaying the changes in the listing data set).
- Batch execution
- Select this option when you want File Manager to create JCL that
reflects the FIND or CHANGE command that you entered on the Command
line. The JCL is presented in an Edit session which you can edit before
submitting.
Batch execution restricts the member selection to the pattern specified in the member field. Batch execution does not produce a pop-up selection panel for member selection. If you leave the member field blank, an asterisk (*) is substituted in the JCL generated. For more information, see FCH (Find/Change).
- Stats off
- When selected, this option ensures that the ISPF statistics for PDS or PDSE members, if present, are not updated. Selecting this option improves performance when processing PDS or PDSE data sets with many members.
- Directory integrity
- Forces an override of the default PDS(E) member processing method
which allows for faster PDS directory access.
This option has significant performance impact. When selected, the members are processed in a way which allows concurrent directory updates as File Manager accesses the members using current directory information.
When not selected, the member processing is performed faster, but may be affected by PDS(E) directory updates, possibly causing I/O errors if the data set is updated concurrently.
- Listing Option
- Use this option to choose the format of the output report.
- 1
- A full report, including each record found or changed.
- 2
- A summary report providing totals for records processed and strings found and changed.
- ISPF Packing
- Provided that the output data set is a sequential, PDS or PDSE
file, an I/O exit routine is not used and the DISP is set to OLD,
select one of these options to control the copy behavior when processing
data that is in ISPF PACK format.
- 1. Asis
- Select this option when you want File Manager to write the output in the same format (packed or unpacked) as the input records. If the input data is packed, it is unpacked for the processing operation, and then written out in ISPF PACK format.
- 2. Unpack
- Select this option when you want File Manager to write the output in unpacked format, regardless of the format of the input records. If the input data is packed, it is unpacked for the processing operation, and then written out without the ISPF PACK format.
- 3. Pack
- Select this option when you want File Manager to write the output in ISPF PACK format, regardless of the format of the input records. If the input data is packed, it is unpacked for the processing operation, and then written out in the ISPF PACK format.
- 4. None
- Select this option when you do not want File Manager to check
for packed records or unpack records for processing. If the input
data is packed, any processing actions operate on the records in their
packed format.
This is the only option allowed when an I/O exit has been specified, or when the data set is not a sequential file or PDS(E) member.
- 5. Skip
- Select this option when you want to halt the processing actions if the input data is packed.
