The function that I want: detect if there is any English letter input from the block: ask and wait?

Here is the method that I came up with:

when green flag clicked
ask [Please type] and wait
if <(answer) contains a> then
say [yes]
end

The problem is that I need to put 26 ‘if…then…’, it is too complicated, is there any easy way to detect the English letter?
Thanks.

You can use the same contains block multiple times by putting it in a loop and iterating over a list of letters.

Create a new list and add every letter you want to detect in it as items.

delete all of [list v]::list
add [a] to [list v]
add [b] to [list v]
add [c] to [list v]
add [d] to [list v]
...

Then, you can make a script like this:

ask [Please type] and wait
set [i v] to [1] // variable used for counting
repeat (length of [list v] :: list) // make the loop repeat for every item
if <(answer) contains (item (i) of [list v] :: list) ?> then // check if the current list item (letter) is in the answer
say [yes]
stop [this script v] // this block is optional - if you want to stop checking once a single lettter is found, keep this block
end
change [i v] by (1) // increment counter to go to the next item
end

@awesome-llama, good idea, thanks.

Or, rather than a list, you can use a text variable containing ‘abcdefg….’ and loop through that. Just a case of using ‘letter i of text’ rather than ‘item i of list’.

@deck26, right, that is another option. Thanks.
