files that were created with the V8 engine.
Using the CONTENTS Procedure to Determine Page Size |
To determine the length of each observation in a Version 8 SAS
data set, you can create a Version 8 SAS data set that contains one observation.
Then run the CONTENTS procedure to determine the observation length. The CONTENTS
procedure displays
Engine/Host-Dependent Information
, including page size and the number of observations per page for uncompressed
SAS data sets. For example, the following input produces a SAS data set plus
PROC CONTENTS output:
data oranges; input variety $ flavor texture looks; total=flavor+texture+looks; datalines; navel 9 8 6 ; proc contents data=oranges; run;The output is shown in CONTENTS Procedure Output.
