"MODE" Funge-98 Standard Modes

Fingerprint ID:0x4d4f4445

This fingerprint, from Cat’s Eye Technologies, implements four modes applicable to IP. It provides the following commands:

H : —

Toggles hovermode on and off. Hovermode is disabled by default. If hovermode is enabled the following commands are altered:

< : —

Decreases X component of delta: in the other words it accelerates delta leftwards.

^ : —

Decreases Y component of delta: in the other words it accelerates delta upwards. Reflects in Unefunge mode.

l : —

Decreases Z component of delta: in the other words it accelerates delta towards lower layers. Reflects in Unefunge and Befunge mode.

> : —

Increases X component of delta: in the other words it accelerates delta rightwards.

v : —

Increases Y component of delta: in the other words it accelerates delta downwards. Reflects in Unefunge mode.

h : —

Increases Z component of delta: in the other words it accelerates delta towards upper layers. Reflects in Unefunge and Befunge mode.

_ : value —

Acts like modified semantics of < and >.

| : value —

Acts like modified semantics of ^ and v. Reflects in Unefunge mode.

m : value —

Acts like modified semantics of l and h. Reflects in Unefunge and Befunge mode.

The original specification didn’t mention about l, h and m commands, but it is logical to extend hovermode to them.

I : —

Toggles invertmode on and off. If invertmode is enabled, IP pushes the value to the bottom instead of the top of the stack.

Q : —

Toggles queuemode on and off. If queuemode is enabled, IP pops the value from the bottom instead of the top of the stack.

S : —

Toggles switchmode on and off. If switchmode is enabled the following commands are altered:

[ : —

Acts like Funge-98 [ command, but also changes the current cell in the Funge space to ].

] : —

Acts like Funge-98 ] command, but also changes the current cell in the Funge space to [.

{ : ... n — offset; ...

Acts like Funge-98 { command, but also changes the current cell in the Funge space to }.

} : offset; ... n —

Acts like Funge-98 } command, but also changes the current cell in the Funge space to {.

( : id^A — idvalue 1

Acts like Funge-98 ( command, but also changes the current cell in the Funge space to ).

) : id^A —

Acts like Funge-98 ) command, but also changes the current cell in the Funge space to (.
