PROC SUMMARY Statement

PRINT NOPRINT

• specifies whether PROC SUMMARY displays the descriptive statistics. By default, PROC SUMMARY produces no display output, but PROC MEANS does produce display output.

• Default: NOPRINT

VAR Statement

Identifies the analysis variables and their order in the results.

Default: 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.

Interaction: 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.
