Problem:

How can an empty idx file be used for rebuilding an ISAM file with a new key structure instead of specifying every key on the rebuild command line with the -k option?

Resolution:

For IDXFORMAT"3" and IDXFORMAT"4" files:

- Copy the empty idx file to the existing dat file.

- now rebuild the data file by specifying the infile only

  rebuild MyFile.dat

  specifying an outfile requires the additional option /d

  rebuild MyFile.dat,NewFile.dat /d

For C-ISAM files = IDXFORMAT"1", please review KB: 23664
