can I delete (or pack) the made history by Zscript?
I made around 100 step macro and It make me say, “good bye my latest history, 100m far away.”
I would like to make one history one macro to the better history viewing.
You can use:
[IPress,Edit:Tool:DelUH]
to delete all the Undo History. But that will delete any history created before your macro.
There is also this command:
[MergeUndo]
which will merge the next undo with the previous one. You would have to put the command in front of every command in your macro (that would generate an undo) to be sure of merging them all.

Thank you for answering! This is really what I need.
but, is it only my problem when using [MergeUndo]?
The Undo indicator still count 100 histories.
My Ctrl+Z undo 100 history back by one touch.
so, it looks packed succefully internal.
Yes, I forgot about that - the counter will show the same but Ctrl+Z will skip back all 100 in one go.

I’m glad to hear it is not the matter only for me.
thank you 
I don’t think I can find a command called MergeUndo in the online documentation, but are there any other commands that aren’t specified in this way?
No consecutive replies are allowed. Please edit your previous reply, or wait for someone to reply to you.
I guess the [MergeUndo] command hasn’t made it into the online docs yet - I’ll correct that. Note that you can always view the most recent zscript command list inside ZBrush by pressing the “Cmd” button in the ZScript palette. The commands will appear in the ZScript Window at the bottom of the interface. (Drag up the handle or press ‘H’ to show.)
Also, you can press the “Export Commands” button in the ZScript palette to export a list of the commands as a text file.
HTH,
Marcus
