-; *** Collapse OS lib copy ***
-; In the process of Forth-ifying Collapse OS, apps will be slowly rewritten to
-; Forth and the concept of ASM libs will become obsolete. To facilitate this
-; transition, I make, right now, a copy of the routines actually used by Forth's
-; native core. This also has the effect of reducing binary size right now and
-; give us an idea of Forth's compactness.
-; These routines below are copy/paste from apps/lib and stdio.

 ; copy (HL) into DE, then exchange the two, utilising the optimised HL instructions.
 ; ld must be done little endian, so least significant byte first.
