May 15, 1998 RHG. Added ~model~ token.
|
||
|
|
|
||
|
|
August 8, 2000 RHG. Changed [%]p (the number of positions for Lex) to 5000.
|
||
|
|
|
||
|
|
August 10, 2000 RHG. Changed [%]e (the number of parse tree nodes) to 2000.
|
||
|
|
|
||
|
|
March 2002 Ulrich Telle Port to C++, using ~flex~ and ~bison~ instead of ~lex~ and ~yacc~.
|
||
|
|
The pattern for floating point numbers is adjusted so that numbers produced by
|
||
|
|
C/C++ programs are interpreted correctly.
|
||
|
|
|
||
|
|
January 29, 2004 RHG. Increased numbers [%]n to 2000 and [%]e to 4000.
|
||
|
|
|
||
|
|
October 14, 2004 RHG Added text and file tokens.
|
||
|
|
|
||
|
|
January 10, 2006 Victor Almeida removed the ~model~ token.
|
||
|
|
|
||
|
|
July 15, 2010 Christian Duentgen added conditionalcommand
