The standard direction for text in input fields and text blocks is left to right, accordingly contents taking up multiple lines are displayed left-aligned. (Exception: amount fields)
However, in some languages, e.g., Arabic, text is written right to left and text is displayed right-aligned.
If for these languages (in the example AR = Arabic) an entry is made in the file TDPARA.INI
[Special Options] RTLUILS=AR
then via
$var = GetContext( "DIRECTION", xxxUIL )
where xxxUIL contains the abbreviation for the language to be used to fill in the field/block, it can be tested whether this language belongs to the “RightToLeftUserInterfaceLanguageS” and, using
SetValues( <Feld/Block>, "P DIRECTION " + $var )
can be set to the relevant text direction. When printing the field in a document, this entry also determines the text direction to be used.
