Just a reminder that CANONICAL Spin2 (that is, compiled by PNut/Propeller Tool/Spin Tools) can do assembly testing without invoking a separate cog. I've never used ALTS but think it will be useful in an upcoming project so I took Andy's suggestion and wrapped it into an inline test. It works as intended. Thanks, Andy!

Inline ASM works in flexspin, too, no need to stress out. Recently a new mode has been added that's even more compatible with PNut (Put {++opt(!fast-inline-asm)} between PUB/PRI and the method name to enable - other compilers treat this as a regular comment)
Lol, that might be a little overkill. Jon was just saying he hasn't tested using Flexspin so can't speak for it. His example assembly will compile in just fine without special controls.
The main reason Eric added that full assembler compatibility switch was to provide compile-time cogRAM allocation warnings for two of my chunky Pasm2 Fcache'd routines that use big RES directives. The default assembler can't do the calculation to give a warning.

Forget the first MOV, and ALTS's D operand is meant to be the index.
'Update pattern here alts PatIdx_, #PWMPatt00 ' PatternIdx added mov PattCurr, 0-0As long as the pattern table is in the cogram (of the same cog that executes the code), the ALTS approach should work. I would write it like that:
alts PatIdx_, #PWMPatt0 ' PatternIdx added to pattern table addr mov PattCurr, 0-0Andy
OK, I was close, just not close enough! Now it works as expected. Nothing like the Prop around !
