Example 22. Example of the abs opcode.

    /* abs.orc */
    ; Initialize the global variables.
    sr = 44100
    kr = 4410
    ksmps = 10
    nchnls = 1

    ; Instrument #1.
    instr 1
      i1 = -6
      i2 = abs(i1)

      print i2
    endin
    /* abs.orc */

    /* abs.sco */
    ; Play Instrument #1 for one second.
    i 1 0 1
    e
    /* abs.sco */

Its output should include lines like:

    instr 1:  i2 = 6.000
