Control Flow
Control flow commands are used to control the flow of the program. All control flow commands use the prefix.
Label
Labels are used to mark locations which can be jumped to from elsewhere in the program. In Nospace, labels are defined by an identifier which consists of a sequence of and terminated by a .
Syntax
| Command | Unobsfucated | |
|---|---|---|
| Nospace | | ZWJ, ZWSP, ZWSP |
| Whitespace |
| Newline, Space, Space |
| Nossembly | Label | - |
Parameters
The Label command requires a unique identifier consisting of a sequence of and terminated by a .
Stack parameters
The Label command takes no stack parameters.
Example
Call
The Call command calls a subroutine. Control is given to the provided label and is returned when the Return command is executed from within the invoked subroutine.
Syntax
| Command | Unobsfucated | |
|---|---|---|
| Nospace | | ZWJ, ZWSP, ZWNJ |
| Whitespace |
| Newline, Space, Tab |
| Nossembly | Call | - |
Parameters
The Call command must be passed the label to invoke.
Stack parameters
The Call command takes no stack parameters.
Example
Jump
The Jump command unconditionally jumps to a label.
Syntax
| Command | Unobsfucated | |
|---|---|---|
| Nospace | | ZWJ, ZWSP, ZWJ |
| Whitespace |
| Newline, Space, Newline |
| Nossembly | Jump | - |
Parameters
The Jump command must be passed the label to jump to.
Stack parameters
The Jump command takes no stack parameters.
Example
JumpZero
The JumpZero conditionally jumps to the specified label if the top item of the stack is 0. The top item of the stack is discarded as part of the command.
Syntax
| Command | Unobsfucated | |
|---|---|---|
| Nospace | | ZWJ, ZWNJ, ZWSP |
| Whitespace |
| Newline, Tab, Space |
| Nossembly | JumpZero | - |
Parameters
The JumpZero command must be passed the label to conditionally jump to.
Stack parameters
Int- the value to evaluate
Example
JumpNegative
The JumpNegative conditionally jumps to the specified label if the top item of the stack is less than 0. The top item of the stack is discarded as part of the command.
Syntax
| Command | Unobsfucated | |
|---|---|---|
| Nospace | | ZWJ, ZWNJ, ZWNJ |
| Whitespace |
| Newline, Tab, Tab |
| Nossembly | JumpNegative | - |
Parameters
The JumpNegative command must be passed the label to conditionally jump to.
Stack parameters
Int- the value to evaluate
Example
Return
The Return command transfers control from a subroutine back to the caller. If the Return command is invoked outside of a subroutine, it ends the execution of the program.
Syntax
| Command | Unobsfucated | |
|---|---|---|
| Nospace | | ZWJ, ZWNJ, ZWJ |
| Whitespace |
| Newline, Tab, Newline |
| Nossembly | Return | - |
Parameters
The Return command takes no parameters.
Stack parameters
The Return command takes no stack parameters.
Example
End
The End command ends the execution of the program.
Syntax
| Command | Unobsfucated | |
|---|---|---|
| Nospace | | ZWJ, ZWJ, ZWJ |
| Whitespace |
| Newline, Newline, Newline |
| Nossembly | End | - |
Parameters
The End command takes no parameters.
Stack parameters
The End command takes no stack parameters.
