SAS Macro Language: Reference

SAS/CONNECT Interfaces

The %SYSRPUT macro statement is submitted with SAS/CONNECT to a remote host to retrieve the value of a macro variable stored on the remote host. %SYSRPUT assigns that value to a macro variable on the local host. %SYSRPUT is similar to the %LET macro statement because it assigns a value to a macro variable. However, %SYSRPUT assigns a value to a variable on the local host, not on the remote host where the statement is processed. The %SYSRPUT statement places the macro variable in the current scope of the local host.

Note: The names of the macro variables on the remote and local hosts must not contain a leading ampersand. [cautionend]

The %SYSRPUT statement is useful for capturing the value of the automatic macro variable SYSINFO and passing that value to the local host. SYSINFO contains return-code information provided by some SAS procedures. Both the UPLOAD and the DOWNLOAD procedures of SAS/CONNECT can update the macro variable SYSINFO and set it to a nonzero value when the procedure terminates due to errors. You can use %SYSRPUT on the remote host to send the value of the SYSINFO macro variable back to the local SAS session. Thus, you can submit a job to the remote host and test whether a PROC UPLOAD or DOWNLOAD step has successfully completed before beginning another step on either the remote host or the local host.

To use %SYSRPUT, you must have invoked a remote SAS display manager session by submitting the DMR option with the SAS command. For details about using %SYSRPUT, see the SAS/CONNECT documentation.

To create a new macro variable or to modify the value of an existing macro variable on a remote host or a server, use the %SYSLPUT macro statement.

Example Using %SYSRPUT to Check the Value of a Return Code on a Remote Host

This example illustrates how to download a file and return information about the success of the step. When remote processing is completed, the job checks the value of the return code stored in RETCODE. Processing continues on the local host if the remote processing is successful. In this example, the %SYSRPUT statement follows a PROC DOWNLOAD step, so the value returned by SYSINFO indicates the success of the PROC DOWNLOAD step:

/* This code executes on the remote host. */
rsubmit;
   proc download data=remote.mydata out=local.mydata;
   run;
         /* RETCODE is on the local host. */
         /* SYSINFO is on the remote host. */
   %sysrput retcode=&sysinfo;
endrsubmit;

   /* This code executes on the local host. */
%macro checkit;
   %if &retcode = 0 %then
      %do;
         further processing on local host
      %end;
%mend checkit;

%checkit

To determine the success or failure of a step executed on a remote host, use the %SYSRPUT macro statement to check the value of the automatic macro variable SYSERR.

For more details and syntax of the %SYSRPUT statement, refer to Chapter 13.
