You could send an event and put the (string-)name of that function in the .extra field. Then you should have the function listen to events (eventhooked), if the function spots 'the name of the function' then you execute it.
This is a way where you never have to do large select-case constructions.

The select-case option is ofcourse also valid but you'll keep updating that code if your function count grows.

Select s$
Case "DoThis"
DoThis ' <- function call
Case "DoThat"
DoThat ' <- function call
EndSelect

You could also use a Hashtable or the TMap like this very generic example:

Type TFunction
	Field Func:Int( args:Object[])
EndType

Global Functions:TMap = New TMap

Function AddFunction( name:String, func:Int( args:Object[]))
	Local fn:TFunction = New TFunction
	fn.Func = func
	Functions.Insert( name, fn)
EndFunction

Function CallFunction:Int( name:String, args:Object[] = Null)
	Local fn:TFunction = TFunction( Functions.ValueForKey( name))
	If fn Then Return fn.Func( args)
	Return False
EndFunction

'
' TEST
'
AddFunction( "test", TestFunction)
CallFunction( "test")
CallFunction( "test", ["testing, testing"])

Function TestFunction:Int( args:Object[])
	If args.Length = 1 Then
		Print "Hello from TestFunction( ~q" + args[0].ToString() + "~q)"
	Else
		Print "Hello from TestFunction()"
	EndIf
EndFunction
