Functions

Global functions

To declare a global function:

Function Identifier [ : ReturnType ] ( Arguments )

	...Statements...

End

ReturnType defaults to Void if omitted.

Arguments is a comma separated list of parameter declarations.

Lambda functions

To declare a lambda function:

...Lambda [ : ReturnType ] ( Parameters )

	...Statements...

End...

Lambda declarations must appear within an expression, and therefore should not start on a new line.

For example:

Local myLambda:=Lambda()
   Print "My Lambda!"
End

myLambda()

To pass a lambda to a function:

SomeFunc( Lambda()
   Print "MyLambda"
End )

Note the closing ) after the End to match the opening ( after SomeFunc.

Function values

Monkey2 supports 'first class' functions.

This means function 'values' can be stored in variables and arrays, passed to other functions and returned from functions.
