@nicnut Hi again
I have never used Processing, so I downloaded it added a udp library via the contributions manager and did some tests with my Pd patch and all it worked fine
The sketch folder also has a Pd patch udp.pd.

You may or may not be using this library though!
I thought this may be of interest

The example sketch also contained these comments
/**

• (./) udp.pde - how to use UDP library as unicast connection
• (cc) 2006, Cousot stephane for The Atelier Hypermedia
• (->) http://hypermedia.loeil.org/processing/
• Create a communication between Processing<->Pure Data @ http://puredata.info/
• This program also requires to run a small program on Pd to exchange data
• (hum!!! for a complete experimentation), you can find the related Pd patch
• at http://hypermedia.loeil.org/processing/udp.pd
• -- note that all Pd input/output messages are completed with the characters
• ";\n". Don't refer to this notation for a normal use. --

@nicnut this seems to work

Hi again @prandam
I am unsure exactly what you require, is this what you are after?
sreadfile-2.pd

I noticed the left inlet of text size was not connected, the left inlet is always the hot inlet, if nothing is connected to it then nothing will happen

you need a [t b s] before [text size]

This plugin hides the menu and title bar on windows 10.
With a F11 function key toggle, but only as full screen

[symbol $1] is a creation argument, is there an existing array of the creation argument name?

@Jona motex/system seems to allow both instances while hcs/sys_gui appears to suspends the calling instance until the second instance is closed
two-pd.pd

Hi,
Writing a [textfile] with cr removes the semicolon that Pd uses as a line break.
I think reading a[ textfile] with cr reinstates the semicolon.
If you intend to use [text define] later it may have been better to have used it here also.
