Conditional Properties

In each statement, if the test expression is true, then the conclusion expression is also assumed to be true. Conditional properties are used to prove theorems.

Function Call Pop Stack (10)

if the following are true:

the line at time t = i
the tab at time t = j
statement at line i, tab j = return rex
stack at time t = [ program context with variables: varis and expression state: (expression state with parent stack: parent_stack arguments: arg_stack values: value_stack line: line tab: tab) and control map: control_map, rest ]
expression state at time t = "end_expr"

then Return Value at time (t + 1) = Return Value at time t
