In OpenEdge Dev Studio you may find some Projects are set with Appbuilder settings which means that the meta code can be set to stop accidental editing of the code. This stop developers mucking up any UIB windows settings.
This however also applies to other code types (.w, .p. cls and more) and so code between the &ANALYZE-SUSPEND and &ANALYZE-RESUME tags will not be editable.
This stops me doing a simple “Select All” with cut & delete options not working. It also prevents quick manual changes to any function definitions.
Enable Editing in OpenEdge Dev Studio
The setting to toggle this is hidden away in :
Windows/Preferences/Progress OpenEdge/Appbuilder/Editor:
[] Make AppBuilder generate code read-only.
