When you use &Developer=YES in a VLF-ONE RAMP session, a small information icon appears in all RAMP screens:
When clicked, the icon displays a small RAMP developer panel that has various options to aid in creating and testing RAMP applications:
For example, the Show hidden 5250 screen button allows you to see the 5250 screen that is sitting behind a navigation error message panel.
You can disable the use of the developer panel in your entry point form by specifying Allowrampdeveloperpanel(False). See.
