The current version of PowerServer does not support all PowerBuilder syntax. Unsupported PowerBuilder syntax falls into two categories:
Category 1: PowerBuilder features that are Client/Server architecture specific, and cannot be implemented in n-Tier Web applications.
Unsupported features in this category must be reworked for n-Tier architecture.
Category 2: PowerBuilder features that are currently unsupported by PowerServer, but will possibly be supported in the future.
the section called “Modifying unsupported features” gives you high-level instructions on how to modify unsupported features. Workarounds for Unsupported Features in Workarounds & APIs Guide provides examples on some common unsupported features and ways to work around them.
