Ken,

Thanks.

I am having trouble getting Run Rev to change the textfont by script. 
If one types into the msg box: "set the textfont of field 1 to 
"courier", nothing happens. Maybe it is necessary to first "select" 
the text?

I would like to be able to script:

put the textfont of field 1 into tFont
set the textfont of field 2 to tFont

But that doesn't work.

In all those instances where I have been able to get the text fonts 
the same for the two fields, the justification algorithm works just 
fine. I am justifiably pleased.

But I need to find a faithful way to get the two fields to agree. I 
am leery of making changes to the original text and applying the 
results to that field. The text is changed with the added (one point 
textsize) spaces. Maybe I'll put  the original text into a custom 
property. Maybe I'll ask the script to clone the original field.

Jim

Al,

The problem with copy and paste is that it doesn't faithfully retain 
all the text properties. It would be best to apply the algorithm 
directly to the field of interest rather than paste from another 
utility field.

And the text is changed with my algorithm--extra spaces are inserted 
and they have to retain their text size, in my case that is 3, in 
order to preserve full justification.

I think what is necessary is a plug-in with a drag and drop facility. 
It should also take the original text, without the added spaces, and 
put it into a custom property so that you would be able to retrieve 
the original text if things didn't work out.  You would need that for 
protection.

Right now I am having trouble with Rev's textfont function.
