prevent print

[Ronein]

Hello

What is the way to prevent print ?

i tried ODS close but it didnt work

proc freq data=sashelp.cars  nlevels;
ods       exclude onewayfreqs;
ods       output
nlevels= want
(keep  =  tablevar nlevels NNonMissLevels NMissLevels
rename = (tablevar=VAR_NAME  nlevels=n_levels));
Run;

Maxim 1: Read the Documentation!
ODS _ALL_ CLOSE;

Prevent the printing of what exactly?

If you just want to prevent the frequencies from printing just use the normal PROC FREQ options for that, no need to delve into how ODS works.

tables _all_ / noprint;

If you want to exclude the ODS output NLEVELS then say so in the ODS EXCLUDE statement. 

1    ods exclude nlevels ;
2    ods output nlevels= want
3      (keep= tablevar nlevels NNonMissLevels NMissLevels
4       rename=(tablevar=VAR_NAME  nlevels=n_levels)
5      )
6    ;
7
8    proc freq data=sashelp.class nlevels;
9     tables _all_ / noprint;
10   run;

NOTE: The data set WORK.WANT has 5 observations and 4 variables.
NOTE: There were 19 observations read from the data set SASHELP.CLASS.
NOTE: PROCEDURE FREQ used (Total process time):
      real time           0.01 seconds
      cpu time            0.00 seconds

If you want to exclude all output use the special ODS keyword ALL.  But make sure to reverse it by adding ODS EXCLUDE NONE when finished with the block of code that needs everything excluded.

ods exclude all;
ods output nlevels= want
  (keep= tablevar nlevels NNonMissLevels NMissLevels
   rename=(tablevar=VAR_NAME  nlevels=n_levels)
  )
;

proc freq data=sashelp.cars  nlevels;
run;

ods exclude none;

Log

1    ods exclude all;
2    ods output nlevels= want
3      (keep= tablevar nlevels NNonMissLevels NMissLevels
4       rename=(tablevar=VAR_NAME  nlevels=n_levels)
5      )
6    ;
7
8    proc freq data=sashelp.cars  nlevels;
9    run;

NOTE: The data set WORK.WANT has 15 observations and 4 variables.

If you close ALL the ODS destinations then the ODS OUTPUT is likely not going to do anything as the there is not going to be any ODS output generated. As I understand it the ODS OUTPUT captures what is sent to the ODS destination into data set(s).

If you don't want the Nlevels ODS output to appear in your default ODS destination you would have to close the ODS and then direct the output to a different ODS destination, such as a document you then ignore. 

But it may help to describe more of what you are attempting to accomplish overall instead of just one bit.

I just want to use the output data set and I dont need the print on screen

Just repeating what @Tom already shared:

tables _all_ / noprint;

Repeat:

If you don't want the PROC FREQ Nlevels ODS output to appear in your default ODS destination you would have to close the ODS and then direct the output to a different ODS destination, such as a document you then ignore. Then close that and restart another ODS destination for your "screen". 

With Proc Document you could  compile the "desired" screen output elements into another document if that is the objection to the "screen" appearance of the Nlevels output from Proc Freq.

There may be other ways to get what you want in the data set but I guarantee it will take a lot more programming.

Issue the ODS _ALL_ CLOSE immediately before ODS OUTPUT.

No need to be that drastic.  Closing all of the ods outputs can cause havoc with environments like SAS/Studio that like to try and control the SAS session.

Instead you can just EXCLUDE the outputs you don't want printed.

1    ods exclude nlevels;
2    ods output nlevels=want;
3    proc freq data=sashelp.class nlevels;
4      tables _all_ / noprint;
5    run;
