OUTPUT MODIFY operates on all applicable output
objects that exist in the active Viewer before the OUTPUT
MODIFY command runs.
OUTPUT MODIFYmust come after any commands that
produce output to which you want OUTPUT MODIFY to
apply.
The effects of multiple SELECT blocks within
a single OUTPUT MODIFY command and the effects of
multiple OUTPUT MODIFY commands are both cumulative.
The main difference between these approaches is that subsequent OUTPUT
MODIFY commands can apply to output objects created by previous OUTPUT
MODIFY commands. For example, if the first OUTPUT
MODIFY command includes a REPORT subcommand,
and a second OUTPUT MODIFY command that immediately
follows it includes IF COMMANDS=[LAST], the changes
that are specified on the second OUTPUT MODIFY command
are applied to the report output created by the first OUTPUT
MODIFY command, not the last command before both OUTPUT
MODIFY commands.
