SAS LSAF: &sysinfo is always 0 after proc compare

jsbyxws — Wed, 07 May 2025 02:42:13 GMT

I am working in SAS LSAF (Life Science Analytics Forum) environment. I found &sysinfo after proc compare did not work since its value is always 0. I tried this simple example:

data a;

a=1;

run;

data b;

a=2;

run;

proc compare base=a comp=b;

run;

%put &sysinfo;

Can you help?

I suggest that you show us the LOG from running your code. Include the log of the two data steps, Proc compare and the output of the %put statement. Copy the code and all the messages from the log then on the forum open a text box using the </> icon that appears above the message window and paste the text.

When I run your code this is my log:

52   data a;
53     a=1;
54   run;

NOTE: The data set WORK.A has 1 observations and 1 variables.
NOTE: DATA statement used (Total process time):
      real time           0.00 seconds
      cpu time            0.01 seconds


55
56   data b;
57     a=2;
58   run;

NOTE: The data set WORK.B has 1 observations and 1 variables.
NOTE: DATA statement used (Total process time):
      real time           0.00 seconds
      cpu time            0.01 seconds


59
60   proc compare base=a comp=b;
61   run;

NOTE: There were 1 observations read from the data set WORK.A.
NOTE: There were 1 observations read from the data set WORK.B.
NOTE: PROCEDURE COMPARE used (Total process time):
      real time           0.00 seconds
      cpu time            0.00 seconds


62
63   %put &sysinfo;
4096

So I am getting 4096 for Sysinfo.

Note, it is a good idea on this forum to always paste example code that will run into a text box. The main message window on this forum will reformat pasted text and can result in data steps that won't run because of those changes.

Thanks a lot for reply!

Just tried again and found the exact result as you had &sysinfo is 4096. Maybe something else happened before which I did not know.

Thanks again for advice about pasting original code and result. Below was the one I just tried.

249 data a; a=1; run;

NOTE: The data set WORK.A has 1 observations and 1 variables.
NOTE: DATA statement used (Total process time):
real time 0.00 seconds
cpu time 0.00 seconds

250 data b; a=2; run;

NOTE: The data set WORK.B has 1 observations and 1 variables.
NOTE: DATA statement used (Total process time):
real time 0.00 seconds
cpu time 0.00 seconds

251 proc compare base=a comp=b;
252 run;

NOTE: There were 1 observations read from the data set WORK.A.
NOTE: There were 1 observations read from the data set WORK.B.
NOTE: The PROCEDURE COMPARE printed pages 7-8.
NOTE: PROCEDURE COMPARE used (Total process time):
real time 0.00 seconds
cpu time 0.00 seconds

253 /* options mprint; */
254 %put &sysinfo;
4096
