In SAS Enterprise Guide and SAS-DI you have the possibility to analyze the code for a SAS-program.

The picture below shows the Analyze Program option in SAS Enterprise Guide.

Analyzing the code should result in a conversion of the SAS-code to a SAS Enterprise Guide flow or SAS-DI flow. But none of these code analyzers are very good. Depending on the complexity of the SAS-code you put into the analyzer, they will leave you with a more or less successful conversion. And more times than not they will fail at doing the job.

But SAS comes with a procedure PROC SCAPROC that does a really good job at analyzing and documenting SAS-code.

Below is an example.

The links below gives you further descriptions of PROC SCAPROC and its options. There’s also a guide on how to do a graphical presentation of the result fra PROC SCAPROC.
