How does one get the cursor to show on and blinking with the INPUT command?

Use the hide and show mouse commands. To make it blink at an inputed speed you simply wait the inputed varible between switching.

Good answer - to the wrong question mind you!

Not 100% sure in DBP, but I don't think you can...

couldn't you just paste an animated sprite at the cursor position? I'll have to test, because I'm not exactly sure the cursor position is updated during input, but you could still detect keypresses in the entry$ buffer and move the graphic over at each press.

Not sure I would use input to get the text though, as I believe there wouldn't be an easy way to continue program flow until enter is pressed. So as long as your willing to do away with input. If it's a must, I will have to think a bit more.

I'll test out the theory in a few minutes, I have to give a friend a ride home.

Make a string, call it mycursor, use the | symbol.
Make a timer for the cursor.
Position the cursor string on the same line as the input with a buffer of how many letters are entered in times by the font size.
Use the timer to either switch on and off or to change it from two colours which would appear to be invisible on one state.
This would allow you to control the symbol, the speed, and its ability to be invisible on any background.

Indi, it wouldn't work using the built-in INPUT command, right?

It allows you to have a prompt string, but it won't allow you to move it along with the cursor in any way - or would it?

I don't use input, except for quick test stubs. Writing your own function gives more flexibility. But I am curious...

Funny how I pictured the blinking cursor to be like the 8-bit Atari's (a white blinking box) or DOS's "_". When I read your post for some reason I thought "|" doesn't sound right, then I looked at the cursor on the screen...

it works with the inbuilt input or your own if:

I, like zenassem was under the impression that DBP was like DBC (and all other procedural BASIC languages) in that when using the Input command, the whole program grinds to a halt while waiting for the user to type something.

As such, you can't do anything - with timers or otherwise until the Enter key had been pressed.

And the cursor - or lack of it - is purely down to the in-build Input command and you can't do anything about it. Or so I thought...

Won't TEXT WIDTH work as well (or is that only DBPro)
