[daip] VLATECR and VLBATECR

[Amy Mioduszewski]

Rick,

OK the difference is that VLBATECR allows you to download files and use 
those in the case that the autodownloading doesn't work or you want to 
use a different file. VLBATECR also forces APARM 1,0, while VLATECR 
allows you to set APARM. I assume you are interested in using APARM 1,1? 
The VLBATECR help file has some instruction on downloading files 
manually, I am not super up on the new way to do it (Eric this out and 
made these changes).  I can change VLATECR to allow files to be input, 
but that won't happen until later this afternoon.

I am ccing daip in case Eric has time to do this before this afternoon.
