ISMF follows a set sequence for list panel processing:
- ISMF executes TSO and ISPF commands (for example, KEYS) before
ISMF line operators.
- ISMF executes the ISMF commands CLEAR, END, and RETURN before
line operators. Entering these commands cancels pending line operators.
- ISMF executes line operators before the ISMF commands for scrolling
and tailoring (UP, DOWN, TOP, BOTTOM, LEFT, RIGHT, FIND, VIEW, SORT,
FILTER, FOLD), and before the PROFILE, SAVE, REFRESH, and RESHOW commands.
For example, if you entered COPY as a line operator and FILTER
on the command line, as shown in Figure 1,
ISMF executes the line operator first. The COPY Entry Panel is displayed
and the COPY command is performed before the FILTER Entry Panel is
displayed.

- If more than one line operator is specified, ISMF starts processing
at the top of the list and continues down until it has processed all
the line operators.
For example, in Figure 2,
COPY executes first, then DUMP, and finally COMPRESS.
