What I can remember about moving a partial string using Unidata input buffer to an output buffer you can use the following:
A(4,8) Which will move the 4th through the 8th character to the currently active output buffer.

It also copies parameter 11 of the primary input buffer to attribute 2 of file buffer 2, and so on.
