Transform for Lookup |
 |
FileMan uses this transform only
during lookup.
The contents of this transform should
be M code that sets the variable X to a new value. X is the only input variable
that is guaranteed to be defined and is equal to the lookup value entered by
the user.
During lookup, if the lookup value is
not found in the index, FileMan will execute the TRANSFORM FOR LOOKUP code to
transform the lookup value X. It will then search this index looking for a
match to the transformed lookup value. |
