Format of a Configuration File for Native COBOL

The configuration file conforms to this format:

Each run-time tunable appears on a new line.
Blank lines are ignored.
A comment line starts with a # character. However, as the configuration file is processed at run-time, we advise that you limit the number of comments, in order to keep to a minimum the time taken to process the configuration file.
The maximum number of characters permitted in a comment line is 80, including any new-line or carriage return characters that might be placed at the end of the line by some editors.
Each space in the definition can be replaced with tabs or more than one space. For example:
```
setenv dd_MYFILE /usr/mydir/myfile 
set cobconfig_error_report=TRUE
```

The format of each tunable is:

set configurable_name=value

where:

configurable_name: The name of the run-time tunable .
value: The value to be assigned to the run-time tunable.
Where value is numeric, a leading zero indicates that the value should be treated as octal (that is, base 8). For example, 07 (octal) is 7 (decimal), while 010 (octal) is 8 (decimal); however, 08 (octal) and 09 (octal) are invalid octal values. Hexadecimal values can also be set by using numeric values that begin with with 0x.
