Definitely the ZXPAND-routine. Tested it on EO with ZXPAND.
Works without, so I need to rewrite that part.
Thanks for quick fix. :D

All is good now Johan and the game is very enjoyable even for some one who plays as bad as me!

I needed a different way to combine reading ZXPAND and keyboard together.
This method is short and working. I might use it as default when I can code both ways of movement.

Manual:

LINGO
-----

Lingo is a 1K lowres game where you need to guess the word the computer has selected.

The computer has 242 words stored in 1K memory. The words appear in a fixed order.
The game starts with input of a number.
You can continue a previous game by typing the number of guessed words sofar.
You type 1 less than the last level shown.
For a first time start you enter 000.

After entering the number the computer stops at the first new word.
To start a next word you press SPACE.
You can now type in a 5 letterword. You can overwrite the word until you press Newline.

After Newline the computer will analyze your input against the word in memory.
When a letter matches the position it will be inverted.
When a letter is in the word on the wrong position it will be shown where you typed it.
When a letter is not in the word it is deleted from the input and shown as "-".

After each turn the cursor is already set for the next input.
If you guessed the word the next wordnumber is shown but the screen is not yet cleared.
With SPACE you start the next word.

When a word is not guessed in 5 tries you press space to restart the same word.

By coincidence, the ROM defines the order, the first and the last word are quite nice too.

Have fun,
Dr Beep
