| Use TDS instead of CWF. You need to use Variable Length Elements Delimited, and don't set the Length property on the last field. |

If the last field is of variable length I suspect an occurs depending clause.
You NEED to have that number and field passed before the 1st occurence of the field...

| You can specify Length Units = End of Bitstream if you want to do it that way. |

Clearly you haven't tried all options, as one of the options was "Use TDS instead".
Also, copybook does not require that you use CWF, in fact some copy books may require that you use TDS.
The only feature of copybooks that require CWF are packed decimals... and that may even be handleable in TDS with binary fields (in 6.1).
Otherwise, please be very specific about a) what you've tried, b) what "not working" means.

in your msg set under msg definiton
-> open it adn expand the tree for messages _
-> keep going till you hiot the elemnts and go to properties under CWF set Length of units to End of bit stream
I think thats all i did, took me a while to figure it out for the first time |

as i hv specified earlier.. only the last fiels of the mesasge is of variable lenght.
this is how the copybook looks like..
01 DATA
03 DATA-AREA
05 ID PIC X(05)
05 TYPE PIC X(05)
05 NBR PIC 9(9)
05 NAME PIC X(30)
Now, the NAME field which is 30 bytes in length in copybook def, manytimes has length less than 30 bytes in the incoming msg.
So when i try to parse the i/p msg.. i get a parsing error saying that the length of that feild is too short.. |

Would that be because your FTP cuts trailing spaces?
Use MQ and the trailing spaces should be there.
