Abstract
A method and apparatus for evaluating expressions in a multi-language debugger. Operandi in an expression are first normalized, and then evaluation routines written in the language of the expression to be evaluated are called. A program storage device, readable by a computer having a memory, tangibly embodying a program of instruction executable by the computer, performs the steps of identifying an operand type for an expression; normalizing the operand; calling a native language routine associated with the expression to produce a result; and un-normalizing the result. Thus, the need for very complex expression evaluation routines is obviated. Further, the native language routines need handle only normalized operandi rather than every variation of each data type.
