- Creating an instance of class with a "null" assignment allows to use extern PHP classes.

3.1 January 2003

- The "using xxx" statement produces a C++ "using namespace xxx;" statement. No effect when compiled to PHP.

2.11

- Now you can use static variables without the need to declare any instance of the class.

2.10

- The language now allows to declare a class or a virtual object just by invoking its constructor.
   Ex: print Object(10)
  is equivalent to:    Object o(10); print o 
- The constructor of an int or a text may be used for conversion purpose.
   Ex:
    text a = "12"

   solp -br xxxx            is equivalent to    solp -b -r xxxx

2.9

- The one-statement "if" and other one-statement control structures (for orthogonality) may be written now without the "let" symbol if the following statement starts with a keyword (break, continue, return, print, echo, define). Ex: if x < y break (instead of if x < y let break).
- Added the "plural" function to built-in.
- You can now pass comments to the target code with the double `` comment symbol.

2.06 June 28, 2002 C++ version, First public release

 The version number is the date for this compiler: 2 = year 2002, 6 = month june, a letter may follow.

1.6a July 15, 2002

- Now the binary operators & | ^ are usable with arrays also, for intersection, union and complement of intersection.  The || and # old operators are deprecated;
- Compound assignment with union of arrays is now available.
- the doXXX cast methods on dynamic object are replaced by toXXX and setXXX are suppressed.
- The Scriptol to PHP compiler is now invoqued by solp on Windows & Linux and the Scriptol to C++ one by solc.

1.6 July 1, 2002

- External variables and constants now can start with an underscore (not Scriptol ones). Ex: $(__FILE__)
- Added the method "empty" to array.
- Added several built-in functions. Look at the reference manual.
- Now "extern" is a tag: you can enclose several external declarations between extern and /extern.

1.5b June 7, 2002

- A variable declared inside the heading of a "for" control structure is now local to the block of statements, for compatibility with ANSI C++.
- The "append" array's method is now useless. Suppressed.
- Now both + and - operators are allowed on an array with a scalar.
- The "merge" method is deprecated, but not suppressed for now.
- In 4.2.1 version, the PHP staff has corrected the "array_unique" function. This may causes some difference when your program use the "unique" virtual method or the union operator.
- Unique now returns void.
- The "main" function has changed for compatibilty with C++.

1.5a May 21, 2002

Arrays are indexed list, dicts are associative ones. The difference is reinforced to not be confused by indices and numerical keys.
- Array and dict are no longer compatibles types.You can't assign one with the other, add them, etc... You still can use the "values()" method to convert a dict to array.
- A "pack()" method replaces the "arrange()" one.
- The "unique" method now return void.
- Splicing a dict with another dict retains the keys (PHP loses them). For array, splicing causes a "pack".

1.5 May 2, 2002

- Implemented an automatic cast for int variables assigned with real numbers. Sorry but this may cause some differences in previously written program but allows for full compatibility with the coming C++ version...
- Option -quiet added to.
- In the last version, not relevant error message may be thrown when an error occur, corrected.

1.4a April 16, 2002

- Method "store" added to array, allowing saving it in a file (no PHP equivalent).

1.4 beta April 11, 2002

- Now you can declare "extern" any PHP variable, constant or function and use it as scriptol object, with control of type at reference or assignment.

1.3 Final April 4, 2002

The final 1.3 version is available for Windows and Linux.

1.3c April 2, 2002

- Static attributes are now allowed. PHP has static methods but lacks for static attributes, however Scriptol bypass this limitation when compiling into PHP.
- Added tests on static methods.
- The "let" final element now is generalized for any one-line statement (along with "?").

1.3b March 26, 2002

- Added "-verbose" to the list of options.
- No any message is displayed when running a program, now (but if -v option is passed).
- The "not in" operator previously was not working on arrays. Corrected.
- The tutorial is now included into the archives.

1.3a Win/Linux March 18, 2002

- The archive is smaller once I have replaced the BCC 5.4 compiler by MingW 2.95.3.
- The Linux version now can run the PHP code once it is compiled.

1.3a Windows March 12, 2002

- Modified some system calls for the program to run under Unix as under Windows.

1.3 beta February 20, 2002

- Now all tests on idents ignore truly case to prevent errors at runtime, as PHP is not case-sensitive (for identifiers of functions).
- The "static" keyword is now recognized by the compiler for a method.

1.2 final February 15, 2002

1.2e beta February 13, 2002

- Improved subscripting. Now the compiler recognizes a statement as ident[i][x..y] , providing that the i element is an list or a text.

1.2d beta February 7, 2002

- Reduced the size of the compiler.
- Now a script is launched directly when the compilation is successful, and thus you do not see difference with an interpreted language! (apart that errors are all detected at compile time, a Net advantage).
- Now an instance of class may be declared in any scope (including another class).
- Conditional assignment with the := operator lets the target assigned if the source is not nil or the target not assigned yet. (This is in level 2.)

1.2c beta January 25, 2002

- The annoying file to include "scriptol.PHP" is no longer required.
- Now splicing is available for text also. Thus slicing and splicing can operate on text, array and dict.

1.2b beta January 21, 2002

- Extended methods to dynamic variables with empty [] indices.
- The method toText of array and toArray of text has been replaced by join and split to avoid eventual confusions.
- The "in" operator can now be used also in composite if.
- The "match" operator now works in any relational expression. The "swap" option added to the define statement.
- The "Match" chapter moved to the new Level II reference manual (this has no effect on the compiler).
- Now an array initializer accepts any expression as element.
- Added to built-in the "swap" function.
- Built-in functions and virtual methods are no longer case-sensitive.

1.2a beta January 17, 2002

- Simplified the language, array and dict are unified with a common set of methods.
- Now dynamic variables have all the methods of any type.
- And thus one can now invoque a method on an element of an array, for example: print myarray[10].upper()
 One can also chain the methods: myarray[10].lower().capitalize()
- Post-casting is a new set of methods that give a type to dynamic variables: doInt(), doText(), etc...and dynamic variables may be changed to typed ones with setInt(), setText(), etc...
- A new type of var is implemented: "function", that allows to pass functions as parameters.
- By assigning "nil", you can now remove an element or a range of an array or dict.
- Added to text the method "dup".

1.1 final January 11, 2002

Implemented inheritance of class.
The method "compare" now compares lexicographically (no case).
The method "identical" performs case-sensitive comparison.

1.0p January 9, 2002

Added the union || operator to complete operators on lists.

1.0n January 7, 2002

Added these methods to text: toInt(), toReal()
Added the toText() method to integer and real (or number).

1.0m January 2, 2002

Support to Java now available.
Methods may be chained now, ex: a ="DEMO"
a.lower.capitalize()   ...returns "Demo"
Now you can assign several variables the elements of array or dict by a multiple assignment..
Multiple assignment allowed to call of function returning a single value.
Added the classical "str" to list of built-in functions. It is equivalent to strval.
Both array and dict now has a sort and a kSort method, the first sorting the values and the second sorting the indexes or keys.

1.0l December 28, 2001

A method may be associated to a literal. For text literal mainly.
Ex: "DEMO".length()     returns 4.

1.00 First version, October 22, 2001

Several updates will follow until the 1.0l one.
