Problem:

Micro Focus supports several internal formats for indexed files, including:

IDXFORMAT"1"

IDXFORMAT"2"

IDXFORMAT"3"

IDXFORMAT"4"

IDXFORMAT"8"

An existing indexed file of unknown format can be examined by the "rebuild" command to determine its type.  Use the "-n" flag of "rebuild" to report the file's properties without actually rebuilding the file, for example:

rebuild -n <filename>

In the output, rebuild indicates the IDXFORMAT in a field named "Format", but uses a different set of descriptions in place of:

IDXFORMAT"1"

IDXFORMAT"2"

IDXFORMAT"3"

IDXFORMAT"4"

IDXFORMAT"8"

Resolution:

The shell script attached to this Knowledgebase article creates and then compiles a COBOL program, which in turn creates files of various IDX format, then the shell script runs "rebuild -n" for each file to show how rebuild behaves.  Just download the script and run it like:  sh doit.sh

It reveals that rebuild reports files types as:

IDXFORMAT"1" --- C-ISAM

IDXFORMAT"2" --- Level II

IDXFORMAT"3" --- IDX-3

IDXFORMAT"4" --- IDX-4

IDXFORMAT"8" --- IDX-8
