In Plato, the bubble help which appears after typing "atan2(" is incorrect.

It should be "REAL FUNCTION ATAN2(REAL Y, real x)"

This does look like a bug.
Version: 8.30 reproduces this incorrect result.

Paul,

The file notes_on_parallel_processing.txt appears to be truncated. ParallelExample3.f95 is missing not / included in the file and does not appear to be elsewhere either. Also there is no do ...

It was the notes on parallel processing that caught my eye. I can make the second example run, but the first example hangs on my machine. This would be a really good topic for an instructional video ...

Hi FK,
There are been a fair bit of discussion of these issues over the past year.
For now, the best way to place you axis labels is via a call back function attached to the %pl using draw_character ...

According to the standard, if the STATUS= clause is omitted, it defaults to STATUS='UNKNOWN', and the status is processor dependent.

What this implies is that if you use OPEN with no STATUS= claus ...

Interesting post which puzzled me as I've never came across this issue before and I don't always use STATUS.

I would use this code instead.

a = 1.0
OPEN (UNIT=10,FILE='test.out')
WR ...

And another suggestion, maybe a way of detecting the first call to the %pl call back function via CLEARWIN_STRING@( STR )

A minor suggestion.

We have the subroutine get_plot_point@(x1,y1,xx1,yy1) which returns the pixel coordinates xx1, yy1, of the real world data x1, y1.

It would make programming interactively wit ...

there is nothing obviously wrong in the code you messaged me with:-

Program k
Implicit none
Real marks(100),sum
Integer n,i
Character *50 file1
file1='marks.dat'
sum=0
Open& ...

I have made a few changes to your code.

Program k
Implicit none
Real marks(100),sum
Integer n,i
sum=0
Open(unit=10,file="marks.dat",status='old')
Read(10,* ...

A short video I made for some of my colleagues. Not the best video on YouTube, but it does show the native %pl in action.

Thanks Paul.

Hi Moorthy, yes I've been working in power system analysis for 30 years - and still get confused with the sign of reactive power (complex power, and positive vars being associated with ...

I have noticed that using %th and %`?rh works as expected and displays the help message.

However %thwinapp

Thanks Paul that does exactly what I was looking for.

Eddie, I take your points on-board. The boxes are hidden in the final application and I do have a help on/off toggle button.
