Can I call functions dynamically?

WindBridges · 29th June 2012, 19:42

I have some strings stored in variables. For example, let $0 = "Foo" and $1 = "Bar". I have two functions that have to be called - MyFuncFoo and MyFuncBar. I have to call these functions by enumerating variables - something like Call "MyFunc$0" and then Call "MyFunc$1". I need such behavior because order of variable's values may vary, and some values may be skipped, so order of function calls will vary too. I know it's not possible to specify function name as string in Call, but may be I can emulate this behavior somehow? or any other way to do that?

GetFunctionAddress (You can also call labels)

But how can it help if parameter for GetFunctionAddress must be static compile-time string not containing any variables?

The other alternative is a function with just a big switch and it would have to know all the names of the functions...
