My customer is running fine with 6.5++ dos with patch 1
in his program it compares a literal value with what turns out be a null - specifically  the program does
 if cval('database')) <> 'jodmc' then
    con jodmc
  endif
 
cval('database') turns out to be a null
 
It works fine on my customers computer.
 
I have 6.5++ dos 1.851  and null no longer compares.
I changed the statement on my computer to
if (cval('database') is null then
and now it connects.
 
Can anyone tell me if I am imagining things?
