Abstract
To facilitate the comparison of strings in logic programming, a hash code is added to each string having a value that depends on the contents of the string. Typically, this hash code is made part of the header for the string along with a string identification number, a number specifying the length of the string and a bit specifying whether the string is a run time string or a compile time string.
