Please describe what you consider to be the important features of this code in a paragraph or two.

Calculates surface displacements and strains for vertical strike-slip point source in horizontal layer above half-space. Based on expressions of Ben-Menahem and Gillon (1970) and Jovanovich et al (1974), it requires user interaction in choosing parameters for a numerical integration.
