tcl script

I extended Bruce Momjian's script for use with my application. It does
insert record into the desired table, but says "pg_recvbuf: unexpected
EOF on client connection. Where is the error?

here is the script that I have named as "inward"

#!/usr/local/pgsql/bin/pgtclsh
set conn [pg_connect test];    # connect to the database

puts -nonewline "Enter first three characters: "    ;# prompt user for
a  code
flush stdout
gets stdin code
                      ;# send the query
set cmd "string toupper $code"
set ucode [eval $cmd]
set res [pg_exec $conn \
"SELECT name,clid \
FROM client\
WHERE upper(substring(name from 1 for 3)) = '$ucode' "]

set ntups [pg_result $res -numTuples]
if {$ntups==0} {puts stdout "No match found"; return} else {
for {set i 0} {$i < $ntups} {incr i} {
puts stdout [pg_result $res -getTuple $i];
}}

puts -nonewline "Enter client number: "    ;# prompt user for a  code
flush stdout

                      ;# send the query

set res [pg_exec $conn \

where job.clid=client.clid and job.clid=$mclid"]

set ntups [pg_result $res -numTuples]

"insert into inmat (clid,jobkey, oc,ratex,indoc,indate,inqty) values
