FORTH can do it indeed, by manipulating the return stack directly. For example:
: foo ( -- ) ." enter foo" cr rdrop exit ." exit foo" cr ;
: bar ( -- ) ." enter bar" cr foo ." exit bar" cr ;
: baz ( -- ) ." enter baz" cr bar ." exit baz" cr ;
gives the output:
enter baz
enter bar
enter foo
exit baz
If your forth doesn't have
rdrop, use
r> drop or define it with:
: rdrop r> r> drop >r ;
I also strongly recall having seen words specifically for this purpose, but I can't find one in this forth (maybe they left it out in modern implementations)
