Oh yes, that's it to a t.
I never did more than one data card repair on the punch at a time, using DUPlicate for a many columns of bad card were readable.
For that client, if we hand keyed data it was on terminal (double keyed and compared).
Cards were only on mark-sense workflow.

So while I knew about tab control (from typing class obviously useful!) I never used it with punch.
