|
\ for a created word (variable, constant...) |
ToDo: |
\ is now an alias in the target voabulary. |
Crossdoc destination ./doc/crossdoc.fd makes no sense when |
\ this means it is no longer necessary to |
cross.fs is uses seperately. jaw |
\ switch between vocabularies for variable |
Do we need this char translation with >address and in branchoffset? |
\ initialization 12may93jaw |
(>body also affected) jaw |
\ discovered error in DOES> |
Clean up mark> and >resolve stuff jaw |
\ replaced !does with (;code) 16may93jaw |
|
\ made complete redesign and |
[THEN] |
\ introduced two vocs method |
|
\ to be asure that the right words |
|
\ are found 08jun93jaw |
|
\ btw: ! works not with 16 bit |
|
\ targets 09jun93jaw |
|
\ added: 2user and value 11jun93jaw |
|
|
|
\ needed? works better now!!! 01mar97jaw |
