If it were disk-based, you could write out the computer generated code
to a data file and then use MERGE (with its limitations) to integrate
the code into the program.

If it must be tape-based then you could use some assembly language
glue to simulate what MERGE does. One possibility would be to install
a hook routine for Console In to feed the new program data.  This is
similar to how CLOAD processes an ASCII Basic file.

In either case, keeping the program running after integration of the
new line(s) is another headache you would have to deal with.
