These options put the transformed independent (IREPLACE) and dependent (DAPPROXIMATIONS) in the output dataset.  I would recommend adding the OUT= option to name the output dataset.

This is a common statement in many procedures , its use is to specify the name of the output dataset and any options to use during output.  See SAS/STAT(R) 9.22 User's Guide for more detail, in particular:

DAPPROXIMATIONS

outputs approximations to transformed dependents

I would suggest you read the documentation (freely available) before using any statistical procedure.
