The output I am trying to capture is in the format "ORD-1234" where the numbers will depends on the record number. it will be 4 digits after the ORD-
There shouldn't be a carriage return.

the command on line 4 that works at present is:
echo "string" | dbserver -h -s | cut -c9-16

where dbserver is a program-specific utility to export data from a specialised database program we have running on the server.
The "string" contains data/commands in a specific coded format that the dbserver program can execute, and this exports another string. the Cut command then outputs characters 9-16 in the format shown above.
This runs OK until I try to assign the output to a variable.
