[TRMW]
dfprint_clip=0
Normally DFPRINT allows the text printed in controls to overflow the boundaries of the containing control. This prevents text from being truncated and therefore from possibly being misleading. However it can cause the appearance of output to be untidy.
From release 4.623, you can force DFPRINT to clip text to the boundary of controls by specifying dfprint_clip=1.
This is a regular [trmw] section setting, and may be set in a [progname] section for application that require special handling.
