Transform for Storage |
 |
FileMan uses this transform only when
setting or killing an entry in the index.
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 internal value of the
field.
TRANSFORM FOR STORAGE can be used on
field-type cross-reference values to transform the internal value of the field
before it is stored as a subscript in the index.
If a match is made on this index
during a lookup, then in order to properly display the resulting index value to
the user, the developer may need to enter code into the TRANSFORM FOR DISPLAY
field to transform the index value back to a displayable format.
