Definition:Trace Table

Definition
Let $$P$$ be a URM program.

The trace table of $$P$$ consists of:
 * The stage of computation;
 * The number of the instruction of $$P$$ that is about to be performed;
 * A list of the contents of all the registers used by $$P$$ at this point.

Thus the trace table is a list of the states of the URM program at each stage.

Example
For example, consider the following URM program:

Let it have the following input:


 * $$r_1 = 7$$
 * $$r_2 = 2$$

It has the following trace table:
