### Result

Returns OK or error.

### Description

Sets page break expression.  
We can calculate this expression when the text box is full in a function call with [DynaPDF.WriteFText](DynaPDFWriteFText.md), [DynaPDF.WriteFTextEx](DynaPDFWriteFTextEx.md), [DynaPDF.WriteStyledText](DynaPDFWriteStyledText.md) or [DynaPDF.WriteStyledTextEx](DynaPDFWriteStyledTextEx.md).  
The expression can call other functions like [DynaPDF.AppendPage](DynaPDFAppendPage.md), [DynaPDF.EndPage](DynaPDFEndPage.md) and [DynaPDF.SetTextRect](DynaPDFSetTextRect.md) of course.  
  
Please make sure your expression does not cause an endless loop or recursion.   
  
You can return in your expression what should happen with next text. Return -1 to cancel write operation.   
If you like to change alignment for next block, return 1 for left alignment, 2 for right alignment, 3 for center alignment or 4 for justify alignment.  
  
You can use [DynaPDF.GetLastTextPosY](DynaPDFGetLastTextPosY.md) to know where the text of the last text block ended.  
If you use [DynaPDF.AppendPage](DynaPDFAppendPage.md), please pass the parameter 1 to not change font.  
### Examples

Set the page break expression:

 Set Variable \[ $r ; Value: MBS ("DynaPDF.SetPageBreakExpression"; $pdf ; "Let ( \[  
  
$CurrentColumn = $CurrentColumn + 1;  
  
t = If ( $CurrentColumn < $ColumnCount ;   
  
 Let ( \[   
 $PosX = $StartPosX + $CurrentColumn \* ($ColumnWidth + $Distance ) \];   
 0) ;   
  
 Let ( \[   
 $PosX = $StartPosX ;   
 $CurrentColumn = 0;   
 a = MBS ( \\"[DynaPDF.EndPage](DynaPDFEndPage.md)\\"; $pdf );   
 a = MBS ( \\"[DynaPDF.AppendPage](DynaPDFAppendPage.md)\\"; $pdf ; 1)\];   
 0)   
);  
  
a = MBS ( \\"[DynaPDF.SetTextRect](DynaPDFSetTextRect.md)\\"; $pdf ; $PosX ; $PosY ; $ColumnWidth ; $ColumnHeight )  
\]; 0 )") \]
