In SAS Enterprise Guide and SAS-DI you have the possibility to analyze the code for a SAS-program.
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.
record '<PATH>' attr expandmacros;
The links below gives you further descriptions of PROC SCAPROC and its options.
