Hmmm - now Peter's message is using Japanese, and there is no
previous Japanese message attached...probably a stupid question, but could there
be some kind of virus that is changing people's settings? Thank
you.

<SPAN
>CHANGES FOR
VERSION 4.31.0 (as compared to 4.30.0)
<P class=MsoNormal
><FONT
face=Symbol size=2><SPAN
><SPAN
><SPAN
>
Workspace window uses "icon font"
set in the Windows settings instead of hard coded Tahoma 8
<P class=MsoNormal
><FONT
face=Symbol size=2><SPAN
><SPAN
><SPAN
>
for better readability and
ClearType(tm) compatibility on WinXP, all dialog windows use now 'MS Shell
Dlg' face name that maps to standard MS Sans Serif on Win 9x/Me/NT and Tahoma
on Win 2K and XP.
<P class=MsoNormal
><FONT
face=Symbol size=2><SPAN
><SPAN
><SPAN
>
rewritten AFL parser, now formula
is parsed and coverted to syntax tree and then interpreted. This would allow
further improvements including compilation. This allowed also to add
loops/if-else statements.
<P class=MsoNormal
><FONT
face=Symbol size=2><SPAN
><SPAN
><SPAN
>
implemented IF/ELSE statement,
WHILE and FOR loops:The same basic 'for' loop in AFL is 2..3 times faster
than in JScriptSyntax follows C++/JScript style:
<SPAN
>while( conditional_expression )
statement;
<SPAN
>for( initializer_part;
conditional_expression; iterator_part )
statement;
<SPAN
>if( conditional_expression )
statement;
<SPAN
>if( conditional_expression )
statement;elsestatement;
<P
><FONT
face=Symbol size=2><SPAN
><SPAN
><SPAN
>
implemented compound statements:
these are blocks of statements enclosedin opening and closing curly brace
<SPAN
>{statement1;statement2;...statementN;}
<SPAN
>compound statement can appear anywhere when simple
statement can.
<SPAN
>For example:
<SPAN
>i = 10;<FONT face="Courier New"
size=2><SPAN
><FONT
face="Courier New">while( i < 20 )<FONT
face="Courier New">{Plot( MA(
Close, i ), "MA" + WriteVal( i, 0 ), colorBlack + i
);i = i +
1;<FONT
face="Courier New">}
<P
><FONT
face=Symbol size=2><SPAN
><SPAN
><SPAN

implemented C-style postfix and
prefix increment/decrement operators
<SPAN
>i = 10;<FONT face="Courier New"
size=2><SPAN
><FONT
face="Courier New">WriteIf( i++ );<FONT
face="Courier New">WriteIf( ++i );<FONT
face="Courier New">WriteIf( i );
<P
><FONT

implemented array element access
(subscript) operator []:
<SPAN
>WriteVal( Close[ 0 ] ); // prints the first bar of
close array
<SPAN
>/* a sample low-level implementation of exponential
moving average in AFL */
<SPAN

<P
><FONT
face="Courier New" size=2>for( i = 1; i <
BarCount; i++ )<SPAN
><FONT
face="Courier New">{myema[ i

face="Courier New">}
<P
><FONT

><SPAN
><SPAN

added built-in constant
'BarCount' that returns number of bars available in arrays (the number of
elements of array)When QuickAFL is turned on it may be less than true
number of bars because QuickAFL feature attempts to use only visible bars (and
few before). You can control how many bars the formula requires using
SetBarsRequired() function
<P
><FONT
face=Symbol size=2><SPAN
><SPAN
><SPAN

implemented infinite-loop
protection. Nice if you forgot to increment counter variable in 'for' loop
:-)
<P

tab key now works without need to
press ALT/CTRL in AFL editors
