i'm having trouble getting the following opcodes to work with arrays of
strings.

init doesn't seem to want to initialize a String array element.

"error:  Unable to find opcode entry for 'init' with matching argument
types:
Found: i init S"

printf seems to misinterpret string array element arguments.

below instr 1 prints 0 four times.

instr 2  behaves as predicted.

i1 0 1
i2 1 1 
e

  sr        =  41000
  kr        =  8
  ksmps     =  5125
  nchnls    =  2
  
  gSdisp    [] init   2
  
    instr 1

;  gSdisp[0] init ""  ;; <---------------doesn't compile "found i init S"
;  gSdisp[1] init ""
  ktime     init      0
  ksig      metro     4
  ktime     +=        ksig
  gSdisp[0] sprintfk "%s %d",gSdisp[1],  ktime    ;; can't tell if these work
  gSdisp[1] strcpyk gSdisp[0]                     ;; can't tell if thses work
            printf    "%s \n",    ksig ,gSdisp[1] ;; <---- prints "0 \n"

    endin

    instr 2
  Sdisp0    init      ""
  Sdisp1    init      ""
  ktime     init      0
  ksig      metro     4
  ktime     +=        ksig
  Sdisp0  sprintfk "%s %f",Sdisp1,  ktime
  Sdisp1  strcpyk Sdisp0
            printf    "%s %f \n",    ktime ,Sdisp1, ktime
    endin

Hi,

I think you cannot use this kind of syntax but = instead of init

i think you must do it in two steps:

1.  Sbla sprintfk "...", args
2. gSArray[0] = Sbla

I can't think of a good reason for not having init for S-vars. Is there any?

You are not getting anything because reading and writing to S-variables
depend on the type of index you use:

instr 1
    gSdisp[0] = ""                                                    
    gSdisp[1] = "0"
    ktime     init      0
    ksig      metro     4
    ktime     +=        ksig
    gSdisp[k(0)] sprintfk "%s %d", gSdisp[k(1)], ktime    
    gSdisp[k(1)] sprintfk "%s", gSdisp[k(0)]
    printf  "%s \n", ksig, gSdisp[k(1)]
endin

Having said that, I get "memory allocate failure" after a couple of
seconds with the code above and with strcpyk it segfaults. I don't
understand why.

Then that's a very good reason for not having it right now. lol.
