MEMCLEAR not allowing casts

[Controls Guy]

Why will MEMCOPY let me cast but MEMCLEAR not?

Code: [Select]

MEMCOPY CustomWP0:UW LastCustomWP0:UW 0x20000 MaxRelayWords

MEMCLEAR LastCustomWP0 MaxRelayCount

Because we're mean.

MEMCOPY is blind. MEMCLEAR is type-aware and does struct initialization. We could probably make it work for simple types, but it wasn't straightforward.

Ah, gotcha.  That makes sense.  I was kind of classing the two together mentally.

In a perfect world, they would be, but 'cleared' isn't always 'zero'. For simple types it is, but the instruction is built around type awareness and casting violates that.
