I've used X-Analysis.  I don't see how it's going to reveal all the
business rules.  Here are some examples of business rules:

custno chain credithold
if not %found()...

-load libl into array-
for i = 1 to maxLibs
lib(x) lookup testLibraryTable
if %found() propagate = *off
endfor
...
100 lines later
...
if propagate
  call copyTransactionToTest
endif

if *in20 = *on
  // display field for 'special attention' is set
  call thisCustomerNeedsSpecialAttention
endif
