LOW values and High values set blank in Linux

We are using Microfocus Visual Devhub Cobol 6.0 with patch 20 and RHEL 8.3 and database is Microsoft SQL Server 2019.

When LANG variable is set as en_US.utf8 by default, then both LOW-VALUES and HIGH-VALUES are being populated as blank, so table browse is getting failed. 

But when the LANG variable is changed to en_US, then LOW-VALUES and HIGH-VALUES are having the expected values of X"00" and X"FF". Please note that all other environment setting remain unchanged. 

Need help to understand the LOW-VALUES and HIGH-VALUES behavior change due to this LANG setting.

Please let us know if any other inputs are required.

Hi Priya,

Regarding the fields that are showing blanks where you expect LOW-VALUES or HIGH-VALUES, how are the values being set? It is from a VALUE clause on the field definition within the COBOL program? Or are the field's contents perhaps being retrieved from a database or file?

Hi Blair,

LOW-VALUES and HIGH-VALUES are not defined in the COBOL program. I hope these values are defined in program collating sequence. 

Below are thr codesnippet where LOW-VALUES/HIGH-VALUES are moved to browse table keys.

MOVE MIR-CO-ID TO WAPPL-CO-ID.
MOVE LOW-VALUES TO WAPPL-CTRY-CD.
MOVE LOW-VALUES TO WAPPL-CRCY-CD.
MOVE WAPPL-KEY TO WAPPL-ENDBR-KEY.
MOVE HIGH-VALUES TO WAPPL-ENDBR-CTRY-CD.
MOVE HIGH-VALUES TO WAPPL-ENDBR-CRCY-CD.

PERFORM APPL-1000-READ-MIN
THRU APPL-1000-READ-MIN-X.
