Hi,
editing the text is not possible.
Using TEXTBLOCK, it is possible to define the maximum width for the box. STW function returns the width of a string, you can use that to specify a character spacing or width factor in the TEXTBLOCK.
Left/right justification or alignment can be set in the PARAGRAPH command.
Here are our tutorials on text formatting.
