I've created double entry applications with SAS/FSP.  Nothing jumped
out and hit me on the side of my head that existed to provide any
real assistance.  What I did was create a 'double' screen, and then
used SCL logic and verify each field.  I've done both single and double
pass double entry.  (I'm calling double pass - double entry to be, 1
person entering the whole 'record' then a seperate 'pass' - usually by
a second person - to re-enter the whole record.  Single pass - double
entry is a single person who enters a single or small number of fields,
then immediately repeats the entry of the same data entry.)  Both cases,
I've created the appropriate 'edit' screens, and then coded the double
entry logic in the SCL behind the screens.  The coding of the SCL
screens is pretty specific to the 'flow' of the application and how it
is intended to be used.  You can code to verify the current field,
combinations of fields or whatever you want, each time 'enter' is hit,
or when the user tries to leave the record (and again, you contol this
with your SCL program flow control and blocks).
So, I guess I'm saying, I don't think you will find any ready made
support in current SAS tools for easy support of double entry systems,
so get familar with your FSE and SCL books.
