For those of you who have updated your AutoCAD to 2004 based products, you now will be able to shorten your Polyedit command line sequence a bit by using the new system variable called PEDITACCEPT.  This new system variable controls the prompt that occurs when a line is selected or non polyline segment.  The "Do you want to turn it into one? <Y>" can be turned off by choosing one of the two options below.

0 - Retains the "Do you want to turn it into one? <Y>" prompt.

1 - The prompt is not displayed and the object will be converted into Polyline.
