You can use the “buffers.append” and “buffers.prepend” functions to add 
text to a buffer.

\starttext

\startbuffer[a]
First
\stopbuffer

\startbuffer[b]
Second
\stopbuffer

\startbuffer[c]
Third
\stopbuffer

\startluacode

buffers.append("b",buffers.getcontent("c"))

buffers.prepend("b",buffers.getcontent("a"))

\stopluacode

\getbuffer[b]

\stoptext
