Yeah, debugging! I like the unoptimize idea; that will make stepping back
through the call history a lot easier. In an unoptimized world, one more 1-
really needs to be done on RDEPTH's return to exclude the address an EXIT in
RDEPTH would return to. In an optimized world I guess Leon's privately
communicated idea is best, include the following in RDEPTH's comment :-)
RDEPTH returns the depth of the return stack as it was when RDEPTH was
called.
Warning: Be sure that RDEPTH is not the last word in a definition!
: RDEPTH ( -- n ) STATUS RP@ - CELL / 2 - ;
: NOP ;
: test1 RDEPTH NOP ; ok
test1 . 4 ok
: test2 RDEPTH . ; ok
test2 4 ok
