I'm trying to write an external procedure to 4D using Think C. I still
havent gotten V2.0 so I'm working with version 1.0.6. From what I could
gather from the manuals provided by ACIUS, the external mover utility
will move the procedure into 4D when it is stored as an application.

So I wrote a simple application in Think C and tried to use the mover 
utility but got error 49. After I created a new external proc file, I
tried to open (select) the external procedure I had written but got
the message that 0 bytes were selected. THen when I clicked on the button
that said >>> right or something like that I got error 49.

Could someone tell me how to write an external in 4D using Think C?
Also how do you pass an array to an external procedure? Is it just 
like passing an array from one C pgm to another?

Thanks
