I thought this would probably be pretty useful for some people.

The first function DB_KeyEntry() creates a string from the keys you've pressed.

The second function DB_Letters(scancode()) returns the letter/symbol that the scancode would stand for.

*I know it sounds similar to inkey$(), but this command can return multiple letters/symbols.*

In the download is an example of the text entry, scancode return for letter/symbol, and multiple letters/symbols return.

A few things:
DB_KeyEntry() is pretty much the same as entyr$(), why do they start with DB, and how come you couldn't make a function to detect whether a certain key is in or not using the entry buffer? This seems very helpful, but at the same time a waste.

Thanks for the help!

Well what I was originally trying to do was make a function that would save what you type to a string. The only problem is I would either have to check each keystate individually, or use inkey$ which would work because it registers the key farthest to the left for example:

Ex. If I'm holding the "G" key and then push down on the "H" key it will register the "G" key first because it's farther to the left on the keyboard.

And the final problem was scancode, because like inkey$ it will only return the key being pushed farthest to the left.

So that's how the second function was created. I also like the second function because if you have the scancode of something you can find out what letter or symbol that code stands for, just by using the function.


I'm not really sure of what the entry$() command is so I didn't bother with it. I don't understand the whole buffer thing, but if you could help out with an explanation of it. I could try and whip something up.

Haven't checked it out yet, but it DOES sound like entry$() (records all keypresses to a single string). However, if your program is a little smarter than entry$() (takes into accound backspace, shift, and other significant keys) then that could be a real help

It takes into account backspace and shift.
