multiple assignments not working in CS7

[joachimheintz]

this works in CS6 but not in CS7 (develop):
iMin,iMax = 5,10

not sure it is already expected to work but want to mention it for compatibility.

I was not aware of this syntax in CS6. Is this commonly used? I'm wondering about the long-term language design implications of this and whether it'll cause issues in the future.

Would love to hear @jpffitch and @vlazzarini 's thoughts on this.

I wasn't aware either. Looks like tuples to me but I never knew we supported them in the old parser.

just to note that it is documented in the manual: https://csound.com/docs/manual/assign.html

well then, looks like we need to keep this in the new parser. This goes back to 2010.

i just checked whether multiple assignments work for init rather than for equal. good news that it already works also in CS7, for instance: instr 1 ia,ib init 1,2 print(ia,ib) endin not sure if this helps to implement it for `ia,ib = 1,2`, too.

I looked more carefilly and multiole assinment iin cs6 is just the usual call of an opcode. There is no fuss about diskin2 have multiple outputs and more than 1 input. so there is issue in =or init,. The syntax is just like elsewhere

• { "=.i", S(ASSIGNM),0, 1, "IIIIIIIIIIIIIIIIIIIIIIII", "m",
  minit, NULL, NULL, NULL },
  { "=.k", S(ASSIGNM),0, 2, "zzzzzzzzzzzzzzzzzzzzzzzz", "z",
  NULL, minit, NULL, NULL },
  In the parser3 however = is treated specially and so needs a rewrite to match the simplicity of cs6
