During the i-time pass only, unconditionally transfer control to the statement labeled by label.
igoto label
where label is in the same instrument block and is not an expression, and where R is one of the Relational operators (<, =, <=, ==, !=) (and = for convenience, see also under Conditional Values).
Here is an example of the igoto opcode. It uses the files igoto.orc and igoto.sco.
Example 188. Example of the igoto opcode.
/* igoto.orc */ ; Initialize the global variables. sr = 44100 kr = 4410 ksmps = 10 nchnls = 1 ; Instrument #1. instr 1 ; Get the value of the 4th p-field from the score. iparam = p4 ; If iparam is 1 then play the high note. ; If not then play the low note. if (iparam == 1) igoto highnote igoto lownote highnote: ifreq = 880 goto playit lownote: ifreq = 440 goto playit playit: ; Print the values of iparam and ifreq. print iparam print ifreq a1 oscil 10000, ifreq, 1 out a1 endin /* igoto.orc */
/* igoto.sco */ ; Table #1: a simple sine wave. f 1 0 32768 10 1 ; p4: 1 = high note, anything else = low note ; Play Instrument #1 for one second, a low note. i 1 0 1 0 ; Play a Instrument #1 for one second, a high note. i 1 1 1 1 e /* igoto.sco */
Its output should include lines like this:
instr 1: iparam = 0.000 instr 1: ifreq = 440.000 instr 1: iparam = 1.000 instr 1: ifreq = 880.000
