Reading specific rows from a large sas7bdat file

[BERENZ]

Is there a way to add functionality to read specific rows from a large sas7bdat file? The issue I'm facing is that I have large SAS files (around 10GB) along with text files (an exact, flat copy of the SAS file). Based on the text file, I can specify the subset of rows that I'm interested in (around 10% of the file).

Another option is to specify a filter while reading, for example, reading rows based on a column. However, I understand that this may be more challenging to implement.
