[Csnd] Help with forward reference (define)

Subject	[Csnd] Help with forward reference (define)
	I'm trying to achieve some sort of hoisting/forward reference where I need to call between two UDOs where one is calling itself and the other one calls the calling function back again. https://ide.csound.com/editor/CcCca1LfX6EndkffwMlG The perfect solution would be passing of a function pointer, since that's not yet in csound, I was hoping there was some sort of opcode which I could use, to define A in this example, and redefine it later? Also any workarounds appreciated!

	Maybe implement the A and B paths in opcode AB and use a 3rd argument to switch between the A path or B path when AB calls itself?

	This cheats a little, by doing a dummy 'declaration' of opcode B, before redefining it later. https://ide.csound.com/editor/plVSlXzHkWiCGWQUvJmt Not sure if that's what you meant.

	Both ideas sound promising, though I tried thorin's idea of defining and then redefining, I forgot why that didn't work, but I'll try again in my use case and report. Thanks a lot for the tips!

	One issue is that Csound doesn't allow redefining an instrument within the same compilation pass. I imagine that is what the issue you ran into is? This has happened to me before and I think this could benefit from a change. My use case is different than this though. The downside is that, if I'm remembering correctly, if you compile a, then b, then a, b would have a reference to the first a, not the latter a.

	It gets a little meta and convoluted, but compilestr and evalstr could be used to workaround. I've updated that example in the IDE. https://ide.csound.com/editor/plVSlXzHkWiCGWQUvJmt Strings and evaluations, it's starting to feel a little lispy Thorin On Sun, Oct 11, 2020 at 10:57 AM Steven Yi <stevenyi@gmail.com> wrote: One issue is that Csound doesn't allow redefining an instrument within the same compilation pass.
