Abstract
Described are a system and method for automatically evaluating system constraints which are represented by strings of symbols. A string of symbols each of the constraints as a function of certain system variables. Each symbol represents either an operator for providing a Boolean result, an operand or a command. Each symbol in the string is serially processed one symbol at a time. If the symbol is representative of an operand, the symbol is pushed onto a stack maintained in a computer readable memory. If the symbol is representative of an operator, the operator is executed to provide a Boolean result based upon one or more operands retrieved from the top of the stack and the Boolean result is pushed onto the stack. If the symbol is representative of a command, the command is conditionally executed based upon a Boolean result retrieved from the top of the stack.
