Use &SYSOUTTRAP to specify the maximum number of lines of TSO/E command output to be saved. If you want to save all the output from a TSO/E command, set &SYSOUTTRAP to a number greater than or equal to the number of output lines that the command produces. Any output lines produced in excess of the &SYSOUTTRAP value are not saved.

To save the output of a single command, set &SYSOUTTRAP to zero after issuing the command. Otherwise, output from subsequent commands may replace the original saved output.
