What about using .resx resource file.

TypeCobol uses a file TypeCobol\Compiler\Diagnostics\Resources\DiagnosticMessages.csv
to store all diagnostics messages. What about using .resx resource file instead.

Yes !
Do we keep some variable of diagnostic message in the code, like

                        DiagnosticUtils.AddError(procedureDivision,
                            "Parameter name does not match to any program parameter: " + orphan,
                            token, code: MessageCode.Warning);

This message use the error code MessageCode.Warning in the CSV which map to this message in the CSV:
Warning: {0} where {0} will be replaced by Parameter name does not match to any program parameter: " + orphan

OR
Do we create more messages in the .resx file so we only have the real variable part in the code.
In this case, we'll have
Warning: Parameter name does not match to any program parameter: {0}" in the resx and only orphan` in the code.

About our DiagnosticMessages.csv file, here's the target to replace it with resx file:

• Category : 1 resx file per category
• Code : message name in the resx file
• Severity : Must be specified in the C# code when you create the message
• MessageTemplate : the value in resx file
• Document;PageNumber;ReferenceText : comment in resx file
