Re: [open-cobol-list] Please double check my tutorial

[Brian Tiffin]

I like this initiative Patrick.

And, if this works out we can add the 'dictionary' to all kinds of
tooling.  Vim supports weblinks for contextual help and
omni-completion, for instance.  The GPS GNAT Ada IDE can take links
for keyword help. An external cobhelp (or some such) could take a
reserved word and dump out a wiki page entry, etcetera, ecetera.

Me likey.

Cheers,
Brian
