In your .jedrc file, make sure that register.sl is loaded, or that
reg_get_registers is autoloaded from register.sl:

   % .jedrc
   
   autoload ("reg_get_registers", "register");
   
After this, add the jingo_mode_hook:

   define jingo_mode_hook ()
   {
      variable reg = reg_get_registers();
      reg["s"] = "a long string that I constantly need";
      reg["foo"] = "another string indexed by foo";
        .
	.
   }

In fact, since the registers are global, I would not bother putting
setting them in a hook at all.  That is, try this in your .jedrc file:

    require ("register");
    $1 = reg_get_registers ();
    $1["s"] = "a long string that I constantly need";
    $1["foo"] = "another string indexed by foo";
      .
      .

Note that you can assign arbitrary names to the registers, e.g., foo.
