Backspace Key

[Marcus]

Is the inkey example useful? I don't remember   Here's an example that makes sense.

Code:

set window "test", 640, 480
set redraw off

' input text with 'inkey'.

' allowed characters.
charFilter = []
for i = 32 to 126  charFilter[i] = true
inputString = ""
blinkTimer = 0
while not keydown(KEY_RETURN)
    blinkTimer = (blinkTimer + 1)%60
    c = inkey()
    while c
        if key(charFilter, c)  inputString = inputString + chr(c)
        elseif c = 8  inputString = left(inputString, len(inputString) - 1)
        c = inkey()
    wend
    set color 0, 0, 0
    cls
    set color 255, 255, 255
    set caret 0, 0
    write "Enter something: " + inputString
    if blinkTimer%60 < 30  write "_"
    redraw
    fwait 60
wend

' or just use 'rln'
wln
write "Enter something else: "
otherInputString = rln()
