It's more subtle than that. The fields have to maintain the same 
relative positions in the input buffer. The input buffer position is 
controlled by the order the fields are defined in DDS, not the order 
they appear on the screen.

Ever wonder why running F4 then F6 from within SDA gives the warning 
message: "The fields are sorted. Check buffer layout." SDA is warning 
you that the I/O buffer may no longer match that expected by the 
program. Because the program in this case is the IBM supplied subsystem 
monitor you have to ensure that changes you make to the sign-on display 
file do not alter the buffer layout expected by that program.

You can swap the visual order as long as you do not changed the 
physical order in the DDS. That is the USERID, PASSWRD, PROGRAM, MENU, 
CURLIB, and UBUFFER must be defined in that order. However, as long as 
you don't change the order you can alter the row and column values to 
display password before user should you have need of such behaviour.

You can also use UBUFFER for your own purposes and add you own I/O 
fields into this area if you reduce UBUFFER size by the same amount. 
You can access these fields from a routing program.
