Re: Keyboard buffer

If you inhibit input will the keystrokes still be buffered? I have never had to deal with this scenario so I don't have a direct answer.

As far as manipulating the buffers the only way I know how to do that is by using the DSM APIs. https://www.ibm.com/docs/en/i/7.5?topic=category-dynamic-screen-manager-apis <https://www.ibm.com/docs/en/i/7.5?topic=category-dynamic-screen-manager-apis>

See the Buffer Manipulation section under Low-Level Services.

You may need to have DSM pop-up the "keep your hands to yourself" window so that you have control over the associated buffer. I'm afraid I've done little with DSM since it was first designed so I can't be sure you can do this but ...

In the middle of an interactive RPGLE program, I need to be able to purge the keyboard buffer. There is a point in the program where it calls a (possibly rather lengthy) function. During this time, it pops up a "DO NOT TOUCH THE KEYBOARD" window, which remains on the screen until the function completes. In the event that the user presses a key (or keys) anyway, I need to purge their keystroke(s) before the program continues. I'm hoping that at least one of the following is possible:

1. Is there a function or API that I can call that will purge the keyboard buffer?

2. Is there a way to directly read keystrokes from the buffer, so I can loop through, read all the keystrokes, and just ignore them? (Something similar to the BASIC INKEY$ function.

I'm open to other suggestions also.

Thank you in advance.
