On-Line vs. Batch Access
You normally run Qedit as an on-line session. You type Qedit commands on your terminal and Qedit prints responses on your terminal. If you redirect stdin or stdlist, Qedit assumes that it is in batch.
Qedit in batch is almost identical to Qedit on-line, except for answering questions. When Qedit asks a question in batch, no one is there to answer it. Therefore, Qedit does not expect an answer from stdin. Qedit assumes that you want your batch task to complete, so it always selects the option that will complete the command successfully. This is normally a "YES" answer, as in "yes, clear the file" or "yes, upshift the line". Qedit prints the question on stdlist, as well as the answer that it has selected for you.
When Qedit encounters an error in batch, no one is there to correct it. Therefore, Qedit normally aborts. However, you can use Set Autocont On to override this abort, instructing Qedit to keep processing after errors in batch.
