1.specifies whether PROC SUMMARY displays the descriptive
statistics. By default, PROC SUMMARY produces no display
output, but PROC MEANS does produce display output.
2.If you omit the VAR statement, then PROC SUMMARY produces
a simple count of observations, whereas PROC MEANS tries to
analyze all the numeric variables that are not listed in the
other statements.
3.If you specify statistics on the PROC SUMMARY statement
and the VAR statement is omitted, then PROC SUMMARY stops
processing and an error message is written to the SAS log.
