+
+### 1.3.2. List of control registers
+
+The zero element of the `c7` tuple is an environment information (which itself is also a tuple). The remaining 255 slots are used for global variables. [`[i] SETGLOB`](/tvm/instructions#f87_-setglob) modifies `c7`, inserting an element with index `i`, [`[i] GETGLOB`](/tvm/instructions#f85_-getglob) reads `i`-th element from `c7`. See [TVM > Registers](/tvm/registers#c7-%E2%80%94-environment-information-and-global-variables) for details.
+
+### 4.4. Continuations as objects
+
+It is possible to construct such objects, however, no high-level language implemented it yet.
+
+### 4.5.7. List of predefined exceptions
+
+Exit code `11` is thrown by [standard function selector](/tvm/registers#c3-—-function-selector) if there is no function with given id. Also it is thrown by [SENDMSG](/tvm/instructions#fb08-sendmsg) in case of invalid message.
+
+### 5.1. Codepages and interoperability of different TVM versions
+
+Currently only codepage `0` implemented. 
+
+### A. Instructions and opcodes
+
+Basic gas price is `10 + b`, not `10 + b + 5r`. See [TVM > Gas](/tvm/gas) for details.
+
+Provided instruction list is obsolete. Consider use [TVM > Instructions](/tvm/instructions).
+
+### B.2. Step function of TVM
+
+"Reference implementation of TVM" and codepages `-1` and `-2` are not implemented yet.
