Syntax

Sdst strcatk Ssrc1, Ssrc2

Examples

Here is an example of the strcatk opcode. Play strcatk.csd

; Example by Jonathan Murphy 2007

    instr 1

  S1	    =  "1"
  S2	    =  " + 1"
  ktrig	    init      0
  kval	    init      2
if (ktrig == 1) then
  S1	    strcatk   S1, S2
  kval	    =  kval + 1
endif
  String    sprintfk  "%s = %d", S1, kval
	    puts      String, kval
  ktrig	    metro     1

Its output should include lines like this:

1 + 1 = 2
1 + 1 + 1 = 3
1 + 1 + 1 + 1 = 4
1 + 1 + 1 + 1 + 1 = 5
1 + 1 + 1 + 1 + 1 + 1 = 6
1 + 1 + 1 + 1 + 1 + 1 + 1 = 7
1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 = 8
1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 = 9
1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 = 10
1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 = 11
1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 = 12
