129 | # BRANCH The set of branches constituting a single choice are hooked |
130 | # together with their "next" pointers, since precedence prevents |
131 | # anything being concatenated to any individual branch. The |
132 | # "next" pointer of the last BRANCH in a choice points to the |
133 | # thing following the whole choice. This is also where the |
134 | # final "next" pointer of each individual branch points; each |
135 | # branch starts with the operand node of a BRANCH node. |
