Scrolling to the first or last record or column

To scroll to the first or last record or first or last column in the data set, type MAX (or M) on the Command line, then press one of the scroll function keys. For example, typing M then pressing the Right function key (F11) scrolls right to the last column.

You can also scroll to the first or last record by entering TOP or BOTTOM on the Command line.

When you perform one of these actions:
  • View or edit KSDS or ESDS data sets that do not fit into available memory.
  • Use in-place editing for KSDS or ESDS data sets (regardless of the file size).
and you use the BOTTOM, DOWN MAX or NEXT MAX commands (to scroll to the end of the data), File Manager uses the best-performing technique to navigate directly to the last record. Similarly, while viewing a ESDS or KSDS, you may navigate directly to a record by entering a RBA or KEY value. In these situations, as File Manager does not know the relative record number, it displays "Record number unknown" in place of the record number and displays '======' in the prefix area. (This message does not signify an error condition.) To make File Manager aware of the number of records in the data set, issue the RECSTATS primary command.

To reset your display after this has occurred, scroll to the top of the data set.

To avoid this situation, scroll down in increments, for example, DOWN 9999, until the end of the data set is reached. Alternatively, if you know the last record number, use the LOCATE command to go to that record. Once File Manager has recognized the record number, you can scroll in any direction, using any of the various scrolling methods, and this display situation does not reoccur.
