Re: VARIABLE<-1> = '' Inconsistent behaviour

At least with maintaining a variable you are in control. ----- Original Message ----- From: Marco Manyevere To: U2 Users Discussion List Sent: Tuesday, February 03, 2004 2:00 AM Subject: Re: VARIABLE<-1> = '' Inconsistent behaviour OK the documentation for REPLACE says something about inserting empty strings. For information flavour it does say the @FM will be added for empty strings without making a distinction between adding to an empty or non empty array.   If this is a feature then it implies major code revisions for me whereever I use the <-1> construct. What would be the shortest/smartest way of adding strings including non significant nulls? I hate to do:   A = '' .... .... INPUT B;  * May be empty IF LEN(B) THEN    A<-1> = B END ELSE    IF LEN(A) THEN       A<-1> = B    END ELSE       A = @FM    END END I have also tested   A<1> = '' A<2> = '' A<3> = 3 A<4> = '' A<5> = 5   and it inserts the @FM as expected but this involves maintaining a counter for the dynamic array.

Whats the explanation? I'm on UV 9.6 [NT] running information flavour.   Regards, Marco   BT Yahoo!
