Mulitple pages help from a program

[sasa]

In a bit more complex test program, it should also be able to show multiple help pages on pressing button "Help" ...

However, it seems (at least in latest public beta) that terminal window which is activated after PRINT commands does not have full abilities inside a running program. The manual also do not show any related command to show fully capable terminal window with scroll abilities.

Using WAIT command between pages is not quite intuitive and making fully capable graphics window with keyboard and menus will take some time...

Is there any undocumented command in the Prime to show fully capable terminal window from a program?
Or perhaps another suitable way?

Making an application in Prime may be the way, however I'm limited with the latest public beta Virtual Calculator on Linux only.

Thanks in advance.
