ctdidx <index file name> <index member #> <flat key file name>
This utility will run either in single user mode or with the FairCom Server. The FairCom Server or single-user transaction processing mode is necessary to dump the keys from an index which supports transaction processing. ctdidx creates a flat file containing each key value at full, uncompressed length followed by the associated record position in long integer, 4-byte, form. ctdidx reads each key in order from the index member designated, 0 for the host index, 1 for the first member, etc., and places the keys in the flat file it creates.
