The selective file dump (SFD) debugging tool writes the contents of specified file records to the real-time tape whenever the ZSELD command is entered. If requested, SFD will also dump all records chained to those specified in the ZSELD command. You can enter the ZSELD command during online operations or included within the input message stream for a PTV test unit. Several SFD requests can be interspersed within the input message stream to locate the point when one or more records are altered. Alternatively, you may only need to verify the contents of a file record at the beginning and end of a test unit.
SFD uses one main storage block to hold the lists of file addresses to be dumped to tape.
See TPF Operations for more information about the ZSELD command.
