Information from a HEPDB database may be copied to a ZEBRA FZ sequential file using the routine HDBTOFZ. This routine can output a single datastructure, the contents of a subdirectory or directory tree with optional selection on perid of validity. The required OPEN and FZFILE statements must have previously been issued for the FZ file before calling this routine (see, for example, PROGRAM HDBTOFZ in the HEPDB PAM file).
