 To call the same variadic function using different variadic arguments,
 different call descriptors are required. For instance to perform
 the equivalent of the C function call
-.str printf("hello\en")
+.cblk
+printf("hello\en")
+.cble
 requires a certain descriptor. To perform the equivalent of
-.str printf("hello, %s\en", name)
+.cblk
+printf("hello, %s\en", name)
+.cble
 requires a different descriptor.
