## strcatk

strcatk — Concatenate strings (k-rate)

## Description

Concatenate two strings and store the result in a variable. strcatk does the concatenation both at initialization and performance time. It is allowed for any of the input arguments to be the same as the output variable.

## Syntax

    Sdst strcatk Ssrc1, Ssrc2

## Examples

Here is an example of the strcatk opcode. It uses the file strcatk.csd.

Example 1043. Example of the strcatk opcode.

    ; 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
