Upgrading obsolete PBLs

When loading PBLs from a previous version (e.g. PowerBuilder 5) into a later version, many error messages may appear in the PowerBuilder Output window. Since inheritance propagates are an issue from the ancestor object to all its descendant objects, some of the errors reported may actually come from a single source.

One common type of error found when upgrading PowerBuilder applications is string corruption. To correct these errors, edit the source code (by selecting Edit Source from the context menu on the error item displayed in the Output window). Errors will disappear when performing a Full Build to the application target.
