SCAPROC Procedure

Overview: SCAPROC Procedure

The SCAPROC procedure implements the SAS Code Analyzer, which captures information about input, output, and the use of macro symbols from a SAS job while it is running. The SAS Code Analyzer can write this information and the information that is in the original SAS file to a file that you specify. The SCAPROC procedure can also generate a grid-enabled job that can concurrently run independent pieces of the job. You can issue the SCAPROC procedure on your operating system's command line or in SAS code in the SAS Editor window.

The following command runs your SAS job with the SAS Code Analyzer from your operating system's command line:

 sas yourjob.sas -initstmt "proc scaproc;  record 'yourjob.txt' ; run;"

sas

is the command used at your site to start SAS.

yourjob.sas

is the name of the SAS job that you want to analyze.

yourjob.txt

is the name of the file that will contain a copy of your SAS code. The file will also contain the comments that are inserted to show input and output information, macro symbol usage, and other aspects of your job. For information about issuing PROC SCAPROC in SAS code, see the examples.

Some tasks of grid-enabled jobs can have dependencies on previous tasks. PROC SCAPROC combines and reorders these tasks based on their dependencies to the preceding tasks. Combining the tasks and submitting them in the same work unit enables faster processing of the tasks. The NOOPTIMIZE argument of the GRID option disables the combining and reordering of tasks of grid-enabled jobs.

Note: For the GRID statement to work, your site has to license SAS Grid Manager or SAS/CONNECT. SAS Grid Manager enables your generated grid job to run on a grid of distributed machines. SAS/CONNECT enables your generated grid job to run on parallel SAS sessions on one symmetric multiprocessing (SMP) machine.
