X

xor
( n1 n2 --- n3 )
"x-or". Return the exclusive OR of n1 and n2.
[
( --- )
"left-bracket". Turn compilation mode off. Words following [ in the input stream are executed rather than being compiled. [ is generally paired with ] in a colon definition. 
      : aword   compiled_words [ executed_words ] compilation words ;
See ].
[']
( --- )
"bracket-tick". A special form of tick that is immediate. It is generally used to retrieve the WA of an immediate word rather than execute it. For example: 
      : got.true   ." True..." ;  immediate
      : got.false  ." False..." ; immediate
      : test       ( tf --- )
                   if   ['] got.true
                   else ['] got.false
                   then
                   execute;
[compile]
( --- )
"bracket-compile". Compile an immediate word into the dictionary. The word following in the input stream is used. 
      : aword   [compile] ['] ;
The effect is the same as ['] aword execute. This is used in traditional Forths to build looping words such as while and repeat.
\
( --- )
"backslash". Comment to end of line. The rest of the line is ignored by the compiler. 
      some words   \ this portion is a comment
]
( --- )
"right bracket". Turn on compilation mode. Text from the input stream is now compiled instead of executed. ] is usually paired with [. : five [ ascii 5 ] literal emit ; When five executes, the digit 5 is displayed on the terminal.
{
( --- )
"left brace". Leave a {} delimited string at here. The string is stored null terminated. Use { interactively for specifying parameter strings to operating system type words such as edit. A typical call is: 
      { filename} here edit
This { cannot be used inside a colon definition.

Note: This word is considered obsolete and has been replaced by ". { will be dropped in a future release.
