6.15 Mathematical text

WinDali includes possibilities to make text appear in the Simulation Interface program with Greek letters and superand subscript.

To use this facility, you have to specify the Name/LongName parameter in calls to Add… functions using the following special characters:

•; Start/end special character section.

• _ Move text down. Creates subscript or moves text back to normal after a superscript.

•^ Move text up . Creates superscript or moves text back to normal after a subscript.

•A string specifying a Greek letter (see below).

Writing the string in lowercase creates the corresponding Greek letter in lowercase. Writing the string in uppercase creates the corresponding Greek letter in uppercase.

Examples:

'c;_;p;^; [kJ/kg-K]' will display as:

'alpha;_;i;^; [W/m;^;2;_;K]' will display as:

The following table shows the strings to include Greek letters:

6.16 Debugging

For debugging purposes you can call the procedure DebugMsg:

Heading

procedure DebugMsg(Msg : PChar; Num : TFloat)

Parameters
Msg	Message to display
Num	An optional number to display (if Num is larger than 1E299 then the number is
Shortcut	not displayed).
Write dbg and press <Ctrl>+J.
Example
DebugMsg('Pressure',P);		{will display for ex. 'Pressure = 1.2'}
DebugMsg('In ModelEq',1E300);		{will display 'In ModelEq'}

The messages you write with DebugMsg will appear on the Debug page in the Message Window in the Simulation Interface Program.
