C	Internal Variable Names

Ski has one combined symbol table for registers and internal variables. (See Section 4.4.2.2, “Registers” and Section 4.4.2.3, “Internal Variables”.) A separate symbol table describes program-deﬁned symbols.

C.1	Internal Variables
$cycles$	Number of “virtual cycles” simulated.
$exited$	The value 0 until the simulated program exits. Then the variable takes the value 1.
$heap$	The address of the bottom of the simulated heap.
$insts$	The number of instructions simulated so far.
