Hello, list, I'm a bit confused about the number of opcodes in Csound.

When I run csound -z, I get this message:

time resolution is 1000.000 ns
0dBFS level = 32768.0
--Csound version 6.12 beta (double samples) Aug 20 2018
[commit: 9c72b2bc95742425f8cde3ea4382e763653ba670]
libsndfile-1.0.28
2152 opcodes

ATSadd           ATSaddnz         ATSbufread       ATScross
ATSinfo          ATSinterpread    ATSpartialtap    ATSread
ATSreadnz        ATSsinnoi        FLbox            FLbutBank
FLbutton         FLcloseButton    FLcolor          FLcolor2
...

and a long list of opcodes. But if I count them, there are 1520 opcodes,
not 2152. What's the meaning of this number, and how are the opcodes
counted?


Best,

lj

Yes, that's it. With -z1 (where all the forms of an opcode are listed
explicitly) the numbers coincide. 

The problem is -z (-z0), that lists each opcode only once, but declares
the same (much bigger) number as -z1. 

I think that it would be preferable that all -zX declared the number of
opcodes actually displayed in the list.

I tend to agree.  Will look at the code

..much easier if the opcode count is at the end of the list 0- saves 
double scanning.  Seems to work

That is perfect. Did you commit?

I see it's updated now, thanks for the improvement.
