Re: [O] #+call split into multiple lines?

[Thomas S. Dye]

Aloha Stefan,

In this situation I often put the arguments in a named Org table and
then write the Babel source code block to take a single argument--the
table name--and parse the information passed in that way.  

#+name: card-table
| cname                   | gname      | photo                 | etc.|
| Dr. Stefan Vollmar      | Stefan     | stefan-vollmar.jpg    | ... |
| Dr. Stefan Vollmar, Jr. | Stefan Jr. | stefan-vollmar-jr.jpg | ... |


#+call: mhead-hcard(card=card-table[0,]) for Stefan

#+call: mhead-hcard(card=card-table[1,]) for Stefan Jr.

If you don't mind writing some extra code for the Babel function, then

#+call: mhead-hcard(card=card-table,gname="Stefan")

etc.

hth,
Tom
