Output Delivery System: The Basics and Beyond

TRACE Examples: Procedures without ODS Output

Some procedures produce ODS output only in certain conditions. Generally, PROC FORMAT is used to create and store formats. However, it can produce output. In the following example, the FMTLIB option is used to generate a listing of the formats stored in the format library called LIBRARY. The output object unique to PROC FORMAT is shown in Figure 6.11.

ODS TRACE ON / LABEL;
proc format library=library fmtlib;
run;
ODS TRACE OFF;

Finally, some procedures don't produce ODS output at all. In this next example, we look at PROC SORT, PROC PRINTTO, and PROC MEANS. Though PROC SORT and PROC PRINTTO do produce output, they do not produce any visible output in the LISTING destination, so there are no ODS output ...
