### Window input Text windows support the **INPUT** command. If you use **INPUT #**, then a cursor is added to the window at the current position. You can then input any text desired, using the left and right arrows to move along the text input so far, or the up and down arrows to move to the start or end of the text. The **DELETE** key deletes the character to the left of the cursor, and the **ENTER** key completes the input. Up to **191** characters can be accepted into each input variable. ### Window definitions Since windows are defined using character squares so for example in LoRes, this means the maximum window size is 16 × 12 (and not 32 × 24). In HiRes however, character squares are considered to be 16 pixels wide, so the maximum window size is still 32 × 24 pixels. ### Memory constraints It should be noted that saving/loading window contents (only available on user windows) is a costly operation. The amount of memory required for each character square is: - 9 bytes (Layer 0) - 16 bytes (Layer 1 HiRes or HiColour) - 64 bytes (Layer 1 LoRes or Layer 2) For example, a 10 x 10 window in Layer 2 requires **6400** bytes of available memory for saving its contents.
