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.

NAME
asa -- interpret carriage-control characters SYNOPSIS
asa [file ...] DESCRIPTION
The asa utility reads files sequentially, mapping FORTRAN carriage-control characters to line-printer control sequences, and writes them to the standard output. The first character of each line is interpreted as a carriage-control character. The following characters are interpreted as follows: <space> Output the rest of the line without change. 0 Output a <newline> character before printing the rest of the line. 1 Output a <formfeed> character before printing the rest of the line. + The trailing <newline> of the previous line is replaced by a <carriage-return> before printing the rest of the line. Lines beginning with characters other than the above are treated as if they begin with <space>. EXIT STATUS
The asa utility exits 0 on success, and >0 if an error occurs. EXAMPLES
To view a file containing the output of a FORTRAN program: asa file To format the output of a FORTRAN program and redirect it to a line-printer: a.out | asa | lpr SEE ALSO
f77(1) STANDARDS
The asa utility conforms to IEEE Std 1003.1-2001 (``POSIX.1''). AUTHORS
