Not too sure the exact problem here, but the MRM is used for fixed length fields only, you can accomodate varying numbers of rows however by using the OCCURS, or OCCURS DEPENDING structures in cobol.
Any queries please shout.
Cheers

| MRM even supports variable length fields in messages. |

...only when you define as (a) null terminated (b) length by a value!!! |

The MRM also supports length encoding 1 and length encoded 2 fields, the latter being standard IBM varying-length character strings. Not all code is written in 'C'!

length encoded 1: 1st byte of storage holds the length of the variable character string excluding the length byte.
length encoded 2: 1st 2 bytes hold the length of the string excluding the length bytes.
null terminated: last byte of the string is binary zeroes (X'00').
Also, you can use an OCCURS DEPENDING type of approach in the MRM, for example by putting your integer count field at the beginning of the message, building your message in a compute node, then RCDing it to a BLOB and removing the first few bytes in another compute node before outputting the message.
