The design of general transform and printing program for seismic catalogue

the seismic catalogue format of SuperSeis (named Eq3 format) is briefly introduced, and the interchange in different seismic catalogues is described in detail. Moreover, the access to Excel files with ODBC (Open Database Connectivity) and Access Database with ADO (ActiveX Data Object) are analyzed, and the direct printing for Eq3 format files is realized. This application package is very small and its operation is very handy, so it is convenient for some users to finish their special works.
