Maria, with ODS you can send anything that appears in a report table to a dataset. I am not a SYSLIN user, but according to the documentation, you can get the standard errors of the estimates into a dataset by adding the statement :
ODS OUTPUT ParameterEstimates=myDataset;
anywhere among the proc statements.
"ParameterEstimates" is the name of the ODS table from which the report table is derived.
