Abstract
A method for automatically instrumenting a computer program for dynamic debugging. Such a computer program comprising source code written in a programming language for executing instructions on the computer. The source code is provided as a sequence of statements in a storage device to the computer. Each of the statements are separated into tokens representing either an operator or at least one operand. A parse tree is built according to a set of rules using the set of tokens. The parse tree is instrumented to create an instrumented parse tree for indicating that an error condition occurred in the computer program during execution. Object code is generated from the instrumented parse tree and stored in a secondary storage device for later execution using an error-checking engine that indicates error conditions present in the computer program.
