2. Type a Recording File Name (also referred to as the Script Data set Name).

   • Enter an existing data set name in the Project, Group, and Type fields. 
   • Type a one- to eight-character data set Member name of the script to be played. If the member name is left blank or a pattern member name is entered, an ISPF member selection list appears.

   Success

   Tip

   If a script data set name does not conform to ISPF naming standards, enter it in the Other Dsn field, including the member name.

   Additional Script and REXX Libs
   You may specify up to three PDS data sets to be concatenated to the play data set. This will allow their script and REXX members to be called by the script being played.

   Success

   Tip

   If three additional script and REXX libraries are too few, you may allocate SYSLIB as follows:
   On the Play Setup screen (ETRM300) screen, the SYSLIB is allocated using 'TSO EX' command on Command ===> line.
   The first data set of SYSLIB allocation must be the recording file HPER.RECBIG.DATA6 and HPER.BIGREC.DATA7 should be in the DS list.
   
   Perform the following steps:
   
   (i) Prepare the data set HPER.DOMTRAV.CLIST(ALLOCSYSL) containing the following lines:
   PROC 0
   SET &HSYSLIB = &STR('HPER.RECBIG.DATA6', +
   'HPER.BIGREC.DATA7')
   ALLOC FILE(SYSLIB) DS(&HSYSLIB)
   SHR REUSE

   (ii) Enter TSO EX 'HPER.DOMTRAV.CLIST(ALLOCSYSL)' on Command ===> line, press Enter

3. Repetition Count repeats script playback n times. Enter a number between 1 and 999.
4. Select a Zoom Mode. Y plays back in zoom mode. N plays back in ISPF mode. R plays back in zoom mode and then returns to ISPF mode when the script completes or when a mismatch occurs. When playback resumes after a mismatch, it resumes in zoom mode.
5. Make a Dubbing selection. Y creates a new version of the original script. N does not create a new script. C creates a new script only if a comparison check occurs during playback of the original script.
   See Explicit-Dubbing-VTAM and Implicit-Dubbing-VTAM for more information on the Y and C options.
6. Select from the list of Playback Options. The Current Values column shows the current setting for each option. Enter a slash (/) next to the desired options.
   • Alter Play/Think Time Option(s) — Display the Play/Think Time Options screen. For more information, see Play and Think Time.
   • Alter Comparison Option(s) — Display the Comparison Options screen. For more information, see Set-Comparison-Options-VTAM.
   • Suppress Play Screen(s) — Select if, during a non-stop playback, you do not want the screens from the domain destination to appear on your physical terminal. This field works in conjunction with think time options 2, 3, and 4.
   • Stop Play — Halt any current playback activity.
7. After making your selections, press Enter.

Play and Think Time

When you type a slash (/) next to Alter Play/Think Time Option(s) on the Play Setup screen and press Enter, the Play/Think Time Options screen appears.

Play/Think Time Options screen

1. Select a playback option. You can select one of four options for interactive or non-stop playback modes on this screen. Option 1 is for interactive playback. Options 2, 3, and 4 are for non-stop playback.
   • 1 — Play back interactively. The script stops and requires user intervention before sending each transaction’s data.
   • 2 — Play back at full speed. Performance Test for VTAM plays the transactions as quickly as the system can run them.
   • 3 — Play back at the think time recorded on the script.
   • 4 — Play back at the think time specified in the Time field.
2. If you selected option 4, you need to specify the Think Time value for each transaction. Time can be specified in seconds (ss), tenths (t) of a second, and hundredths (h) of a second. For example, 00 75 specifies 3/4 of a second think time.
3. If you selected option 3 or 4, you can apply a percentage figure to the think time. For example, to play back a script with half the original think time, select option 3 and type 50 in this field.
4. After making your selections, press Enter to continue. You will return to the Play Setup screen.
