(PowerBuilder) Iterate over Matching Filenames

Iterates over files within a .zip that match a pattern. In this case, the pattern is "*.pem". This example will open a .zip containing files of type .txt, .cer, .pem, and possibly others, and will iterate over only the .pem files.

Note: This example requires Chilkat v11.0.0 or greater.
