QEDITCOUNT JCW
Qedit has a JCW (like a variable) that keeps track of how many lines were processed by the last command: QEDITCOUNT. This JCW is updated after those commands that can print a total: List, Delete, Add-file, Add-move, Add-copy, Append, Change, Divide, Glue, Justify, Keep, Merge, Proc, and Text. The line count is truncated at 32,000.
