Dubbing Scripts (VTAM)

Dubbing is when you record one script while playing back another. You can use dubbing to:

  • Combine multiple scripts into one.
  • Update an existing script with new screen images.
  • Add transactions to the end or middle of a script.
  • Update an existing script with new or additional inputs.
  • Remove transactions from a script.

Dubbing copies row masks and generic masks from the old script to the new script, however, encrypted fields will not be encrypted in the new script. You can use online masking during dubbing to add or delete masks. Performance Test for VTAM comments are also copied during the dubbing.

Tip

REXX statements in the original script are not copied, but the dubbed script contains all transactions initiated via the REXX statements (for example, the script statements resulting from the REXX statements).

You can control online dubbing in two ways:

  • Explicitly using RECORD and PLAY commands.
  • Implicitly using the Dubbing field on the Play Setup screen.

You can also dub using batch processing. See Unattended-Playback-Dubbing-and-Comparison-for-3270-and-LU0-Scripts-VTAM for information.
