Purpose
The purpose of compiling Prolog code to the more low-level WAM code is to make subsequent interpretation of the Prolog program more efficient. Prolog code is reasonably easy to translate to WAM instructions which can be more efficiently interpreted. Also, subsequent code improvements and compilation to native code are often easier to perform on the more low-level representation.

Famous quotes containing the word purpose:
“To me the sole hope of human salvation lies in teaching Man to regard himself as an experiment in the realization of God, to regard his hands as God’s hand, his brain as God’s brain, his purpose as God’s purpose. He must regard God as a helpless Longing, which longed him into existence by its desperate need for an executive organ.”
—George Bernard Shaw (1856–1950)
“Man, her last work, who seemed so fair,
Such splendid purpose in his eyes,
Who rolled the psalm to wintry skies,
Who built him fanes of fruitless prayer,
Who trusted God was love indeed
And love Creation’s final law—
Though Nature, red in tooth and claw
With ravine, shrieked against his creed—”
—Alfred Tennyson (1809–1892)
“Thus one can observe that those who proclaim piety as their goal and purpose usually turn into hypocrites.”
—Johann Wolfgang Von Goethe (1749–1832)
