input str3 code str29 value
"A " "test1test1test1test1。"
"A " "test2test2test2test2。"
"A " "test3test3test3test3。"
"B " "test1test1test1test1。"
"B " "test2test2test2test2。"
"B " "test3test3test3test3。"
"B " "test4test4test4test4。"
"C " "test1test1test1test1。"
"C "  "test2test2test2test2。"
end

The results I want to achieve are:
code value
A test1test1test1test1。test2test2test2test2。test3tes t3test3test3。
B test1test1test1test1。test2test2test2test2。test3tes t3test3test3。test4test4test4test4。
C test1test1test1test1。test2test2test2test2。
