## Detailed Description

Helper tool, which allows to transfere some configurable properties to HFileCnv.

It is useful to e.g. increase the default file parameters like LRECL, mode , etc... In particular it is nesessary to obtain *LARGE* HBOOK-files

The tool has 3 properties

- LRECL : the default record length (default = 1024), it could increased to increase the file capacity.
- NRECL : Number of records (used only if "Q" specified for the MODE)
- MODE : HROPEN mode, (the default value is "P"). "PQ" or even "PQE" should be used for creation of *HUGE* files.

  Attention:
    If "LRECL" if different from the default value, do not forget in PAW (in the command "HI/FILE") to specify the "LRECL" parameters. Note that if the recond length is smaller than 8192, PAW is able to autmatically determine the correct record length if "LRECL" parameter is set to 0 for the command "HI/FILE"
  The recommended setup to produce *HUGE* HBOOK files:

- LRECL=4096
- NRECL=512000
- MODE="PQE"
