It not exactly difficult but first stop writing in upper case, use normal text
and case e.g, the same as this!
1. Remove leading spaces so that Cobol text starts at column 1 for all
sections and division headers and col 2 or more for all others.
2. Replace all comment lines containing '* ' with '*>'
3. Add as line one but starting at column 8 >>source free
4. Cobol does not require all text in upper case so change case to suite your
needs.
5. Upgrade open cobol to version 1.1 or later
[Note that my email editor as messed up spacing in code so that left hand
start position is moved left]
