 +Note that the check on CFA's ''%%dasa @ @+ =%%'' is only correct for ITC code.\\
 +For other systems these lines need adaptation.\\
 +Not in Generic Forth: ''%%WITHIN  CELL-  1-  @+  <>%%''\\

 +
 +An example of its use, disassemble ''%%DUP%%'', ''%%?DUP%%'' & ''%%DROP%%'' in noForth:
 +
 +<code>
 +das dup
 + 4BF0:  K  4BF2   --- cfa ---
 + 4BF2: $   8324   #2   sp SUB

 +^Command     ^Example            ^Purpose                              ^
 +|''%%DAS%%'' |''%%DAS DUP%%''    |Disassemble from the word ''%%DUP%%''|
 +|''%%MDAS%%''|''%%<addr> MDAS%%''|Disassemble from ''%%<addr>%%''      |
 +
 +Each time the space bar is hit, a new line is disassembled. When any other key is hit the disassembly stops!
