registers, programmatically

Dear fellow jedders,

 

I'd like to pre-fill a number of registers programatically upon a mode's start hook.

 

For instance, my jingo_mode_hook in .jedrc would have a line such as:

 

Register_Buffer_Arrays [83] = "a long string that I constantly need";

 

And I could then call register "s" (115-32=83, right?) and see the said long string inserted...

 

Sounds easy enough but I'm obviously not doing this properly with Register_Buffer_Arrays because it doesn't work and (the very cool) register_mode  shows no registers being loaded in that way.

 

Could anyone kindly point me in the right direction?

 

Thanks in advance and regards to all,

 

Alain
