Gets a Range of field values for local or related field. Returns a hard return delineated list.

This function does not seem to behave as expected if the last field in the found set is null.
For example, in a found set of 10 records, the "Nothing" field is all Null values. I would expect to have this
Valuecount(getfieldlist(Table::Nothing, 1, get(foundcount)))
to return "10" (for the the ten null values).
Instead this returns 9.
In fact, I've had some issues with this if ONLY the last field is Null.

|Didn't want to create new function entry, as this is basically the same. I use this all the time, but I only ever use it to obtain complete lists of all field values (including blank) for foundset. It will be a value list of the exact length of the foundset (carriage returns within values will have been escaped). And I use it for really large foundsets. So I switched it to tailend recursion to enable up to 50k, and created a handler function:
GetFieldList ( fieldName )
// Usage: GetFieldList ( Table::FieldName ) or GetFieldList ( GetField("Table::FieldName" ) )
GetFieldList_part ( fieldName ; 1 ; Get ( FoundCount ) ; "" )
GetFieldList_part ( _fieldName ; _start ; _end ; _valueList )
// Switched to tail end, 2012, Thomas Seidler - to allow 50k
_thisVal = Substitute( GetNthRecord ( _fieldName ; _start ) ; "¶"; "\¶" ) ;
_start < _end ;
GetFieldList_part ( _fieldName ; _start + 1 ; _end ; _valueList & _thisVal & "¶" ) ;
_valueList & _thisVal & If(IsEmpty(_thisVal);"¶")
