Properties:

Default: IDXFORMAT"0"
Phase: Syntax check
$SET: Any

Dependencies:

Set to IDXFORMAT"integer" immediately by FILETYPE"integer".

DIALECT"RM" sets IDXFORMAT"21" immediately.

Comments:

By default, IDXFORMATs 17-21 are unavailable under Enterprise Server. You must ensure the ACUFH and ESACUFH configuration options are both set to ON to use these formats.

In cases where the INTEROP and IDXFORMAT settings conflict, the INTEROP setting will override the IDXFORMAT setting.

If you are using Fileshare, IDXFORMATs 17 and 21 do not provide transaction processing capabilities by default. You must configure it on a file-by-file basis using the Virtual File Handler option (/ap) when specifying the file in your database reference file. For example, when you access the following file through Fileshare, it is additionally re-directed to the ACUFH file handler, where transactional support can be provided:
Fs /d dbase.ref /f acufile1.dat /ap ACUFH

Setting the IDXFORMAT using this Compiler directive overrides the index format setting specified in the file handler configuration file.

Specifying 4 might make the files larger than their IDXFORMAT"3" equivalents.

Micro Focus Level II format files are compatible with Micro Focus products such as Level II COBOL, Professional COBOL V1.2, and VS COBOL Workbench versions up to and including V1.3.
