+# Pitmachine
+A pitmachine is an abstract register machine for executing pitcode.
+
+The pitmachine assembly language is JSON. The instructions field contains an array of labels and instructions. Labels are the targets of branch instructions. They are simple text. Slots are elements in an activation frame. They are designated by a small positive integer. Slots are the general registers of the pitmachine. Slots hold the arguments, variables, and temporaries of a function invocation.
+
+{
+    "name": "program_name",
+    "data": {⸳⸳⸳},
+    "source": "...",
+The labels record associates labels with tokens for use by debuggers.
+
+    "labels": {
+        "entry": token,
+        "beyond": token,
+        ...
+    },
+The instructions array is a list of instructions and labels.
+
+    instructions: [
+A statement label:
+
+        "entry",
+go to beyond:
+
+        ["jump", "beyond"],
+assign slot 8: pi / 2

+        ["access", 13, {"kind": "name", "name": "pi", "make": "intrinsic", ⸳⸳⸳}],
