'depends' clause in complex flat file (CFF) stage

[bigpoppa]

DS Server, 6.0r3 on SUN
-----------------------
I am trying to turn the following record into a 'table' using the CFF stage:
-------
4a0123c
-------

The fields are:

Field d, dec (1) - the 4
Field a, char(1) - the 'a'
Field b, char(1) - the '0,1,2,3', occurs up to 4 times, depends on field 'd'.
Field c, char(1) - the 'c'.

The result of the cff should be
-------
d a b c
-------
4 a 0 c
4 a 1 c
4 a 2 c
4 a 3 c

When I use the cff stage, my column definitions are
----------
lvl field
----------
05 d
05 a
05 b occurs 4, depends on d
05 c

The result of the CFF stage is:
-------
d a b c
-------
4 a 0 c
4 a 1 c
4 a 2 c
4 a 3 c
4 a c c
4 a c
4 a c
4 a c
4 a c
4 a c

Why is it giving me 10 records? The first 4 are right, the last 6 are wrong. Has anyone encountered this issue? If I change the number of occurs to '5' for field b, then all of the "c"s in the output turn into '?'s. If I change the # of occurs to 3, then all of the "c"s turn into '3's. If I change the # of occurs to 20, DataStage thinks that the data source is empty. This is weird, right?

Any help is appreciated,
BP

Thanks for the input.

We solved the problem by padding the occurs field with spaces until the field was the size of MAX_NUM_OCCURENCES * LENGTH OF FIELD. Then we sent the padded file thru the CFF stage, and we get the table with a lot of NULLs in the occurs field. Oh well..

It seems like ASCL should grey out the 'depending' on drop down if it doesn't work.
