Re: BISYNC vs ASYNCH programming

[Patrick Townsend <townsend@xxxxxxxxxxxxxx>]

Eric,

There are some differences in how Bisynch and Asynch operate with ICF 
files, but not a whole lot. If you have the Harbinger (formerly Premenos) 
package you can probably write your own communications module and plug it 
in. Or just receive to a file and use file processing to import the file.

One important point: many Asynch EDI interfaces use Xmodem, Ymodem or 
Zmodem to transfer files. You would need a third party package to support 
this on the AS/400. A better choice would be to use FTP. And you don't need 
to install expensive frame relay connections to use FTP. Are you 
communicating with a value added network like Advantis, or going direct 
with a trading partner?
