I am writing a command processor to run on NetView and I had a couple of
concerns about the best way to approach some problems.  The code uses
the NetView presentation services to send a 3270 data stream to the
terminal (erase/write) and waits for a response from the user (aid '7D'/
enter).  The problem I am confronted with is how to take the input
from the screen and disect it.  If the user only fills in 1 field (which
should occur most of the time) then I get the aid, cursor location, sba
, addr and then the field of data (i.e.; x'7D 4DC9 11 4CF8'+field of data).
If the user fills in all 13 fields then I obviously receive 13 sba's,
addr's and 13 fields of data.  What is the best way to move this data
from the input area to the work fields.

What I am trying to do is build a table which contains 13 sets of information.
The first 2 bytes contain a addr (i.e.; x'4CF8'), the next 4 bytes contain
the address of the field I want to move the input into, and the last 4 bytes
contain the length of the field.  When I receive my input I find the 2 bytes
after the sba (x'11') and compare that to my table.  When I match I then
EXECUTE a move using the length entry in my table and the address in my
table to move the data from the input area to the work area!  Isn't this a
roundabout way of performing this type of function?
