Your development environment contains a generic 5250 form wrapper named DF_WRAPO.

You can use it as a wrapper with any 5250 screen by doing this in your RAMP arrival script:

SHOW_CURRENT_FORM(true,"DF_WRAPO");

When executed it looks something like this:

Visual LANSA Version 15 > Using DF_WRAPO to Understand, Experiment or Trace > using df_wrapo to understand experiment or trace.jpg

You can use DF_WRAPO to help understand how wrappers are executed, or even to trace out an unusual situation.

If you don't have DF_WRAPO available, you can create a Visual LANSA reusable part just like it from this source code.

Note that the wrapper works generically because of the code below in blue: * ------------------------------------------------------------------------------------------- * This is a generic RAMP 5250 form wrapper that can be used for testing/debugging
