KEY (macro definition)

---

KEY key_id, string_value

Defines the string macro for function key key_id. Only the first 15 characters of string_value are stored.

Parameters

• key_id is a numeric expression in the range [1 to 15].
• string value is a string expression.

Notes

• If key_id is not in the prescribed range, an error is raised.
• If string_value is the empty string or the first character of string_value is CHR$(0), the function key macro is switched off and subsequent catching of the associated function key with INKEY$ is enabled.

Errors

• key_id is not in [-32768 to 32767]: Overflow.
• key_id is not in [1 to 255]: Illegal function call.
• key_id has a string value: Type mismatch.

KEY (macro list)

---

KEY LIST

Prints a list of the 15 function keys with the function-key macros defined for those keys to the console.

Most characters are represented by their symbol equivalent in the current codepage. However, some characters get a different representation, which is a symbolic representation of the effect as control characters on the screen.

KEY (macro toggle)

---

KEY {ON|OFF}

Toggles function-key macros ON or OFF.
