Hallo dear CsoundPeople !

I try to use the opcode "tableseg" or "tablexseg" in the example of the
manual, but  PCCsound.1(Version3.47) says: "no legal opcode":

ktime   line 			0, p3, 3              ; 3 = p3 ?
		tablexseg		1, p3*.5, 2, p3*.5, 3
apv		vpvoc			ktime, 1, "pvoc.file"

with

f1 0 256 5 .001 128 1 128 .001
f2 0 256 5 1 128 .001 128 1
f3 0 256 7 1 256 1

¿¿  "tablexseg  no legal opcode" !   

Why not?	
 
Thanks
Peter
