Saving data to Lookup

[Shuman, Mike]

System:  Windows XP Pro
filePro Ver.  5.0.09DN9
 
Situation:
 
Input process does lookup into transaction file to obtain
transaction number.  Process adds "1" to transaction
number and writes it back to lookup file.
 
User can break out of input process at any time without
saving the record currently being keyed.  Lookup procedure
has already incremented and written the next transaction
number.
 
Problem:
 
How to make certain that the current record is being saved
before writing the next transaction number back to the 
lookup file.
 
There are over 50 entry fields on the screen.  Only one
is must fill.  User can save record at any of the other
fields.
@wlfxx process to check for <Esc> before writing back to
the lookup file would work but....... Lot of code and
hoping for a simple way out.
 
Thanks ahead of time for any ideas.
