The function invoked by `g' and `G' is not suitable for writing
programs, because it is not designed properly for that.  It should
accept a programmatic argument which identifies the cell to jump to;
but instead it examines the contents of the input buffer and jumps to
the cell it finds identified there, or to cell 0 if the buffer is
empty.  There is no useful way to use this function to jump to a
particular cell.

One of my patches addresses this problem by making `cursor_jump' more
generic, and changing the name of the old function to
`cursor_jump_input'.
