Hi Eddie!

Thanks for the hints.

Respect to reporting the error caused by the recursive re-entrance - may be easier would be to have the ability to switch this diagnostics off for the specific callbacks which have the chance to congest. These are all the callbacks like in
Code:
i=winio@('%^gr[...]',ix,iy, cb_mouseMove)

Code:
i=winio@('%^pl[...]',ix,iy, cb_mouseMove)

Code:
i=winio@('%^og[...]',ix,iy, cb_mouseMove)

Code:
i=winio@('%^bm[...]', cb_Plot)

Code:
i=winio@('%^bt[...]', cb_Plot)

Code:
i=winio@('%^tt[...]', cb_Plot)

etc.
Before (say, a year ago) the method worked to introduce the global var!able iAmBusyProcessingSh!t and check as first statement of callback if it is 0 or 1. If it is 1 you immediately exit. If it is 0 then change it to iAmBusyProcessingSh!t=1 and stay 1 till the plot ends only becoming iAmBusyProcessingSh!t=0 at the exit of callback function.

But recently something changed and you get the program stop immediately at the entrance of callback before any executable statements succeed to handle the situation

Dan

I would need a simple working program that illustrates the failure before making any comment.

Today i was running the long task, all was fine, but after closing and calling the plot for second time i got the crash "Too many links specified for %PL plot" in the line winop@("%pl[link=lines]"). Holy smoke...If Clearwin instead told me that there will be a crash i'd aborted this line and fixed the issue later (hell know what that error means and how it happened, all other dozens of WINIOPs were not affected but this one decided to kick in. May be it does not like my %lw... so many choices and possibilities for conflicts).


I finally cornered the source of this bug though in the extracted demo the bug is not reproduced. The reason was in the relatively new option

CALL winop@("%pl[gridlines]")

When i remove it the code does not crash when i close and open the same window with gfidlines again. Gridlines work perfectly in several other cases but this one crash with the error on the line

call winop@("%pl[link-none]")

If i remove this line the error moves on the next winop@ and so on.

Another observation is that winop@("%pl[gridlines]") not always has any effect (does not plot any gridlines) with this specific subprogram

UPDATE:
I think found the reason for the crash.
Things are that CALL winop@("%pl[gridlines]") has to be placed before i=winio@("%pl[options],.....) but i was placed it after. It appears gridline option is sensitive to this matter

To my mind the order should make no difference.

Dan,

Bearing in mind Paul's comment, was the call for gridlines placed immediately before/after the %pl[options] or are there other lines betwen them which might be implicated in the problem ?

John,
Look at this simple example
Code:
   use clrwin
   parameter (N=5)
   real*8 X(N), Y(N)
   Data X/1e1, 1e2, 1e3,  1e4, 1e5/
   Data Y/2.2, 66, 8333, 1111, 777/

   i=winio@('%fn[Tahoma]%bf%ts&',2.3d0)
   CALL winop@("%pl[gridlines]")
   call winop@("%pl[axes_pen=3,frame_pen=3,width=3,x_axis='X Axis Title',y_axis='Y Axis Title']")
   i=winio@('%ww%pv%pl[native,framed,x_array,scale=log_log,N_GRAPHS=1]&', 925,700, n, X, Y)
   i=winio@('%es')
   end


If you place CALL winop@("%pl[gridlines]") after i=winio@('%ww%pv%pl[native... (I specially made for that %es as a separate line) the gridlines are not plotted.
Code:
   use clrwin
   parameter (N=5)
   real*8 X(N), Y(N)
   Data X/1e1, 1e2, 1e3,  1e4, 1e5/
   Data Y/2.2, 66, 8333, 1111, 777/

   i=winio@('%fn[Tahoma]%bf%ts&',2.3d0)
   call winop@("%pl[axes_pen=3,frame_pen=3,width=3,x_axis='X Axis Title',y_axis='Y Axis Title']")
   i=winio@('%ww%pv%pl[native,framed,x_array,scale=log_log,N_GRAPHS=1]&', 925,700, n, X, Y)
   CALL winop@("%pl[gridlines]")
   i=winio@('%es')
   end


In more complex situation the wrongly positioned gridlines will cause conflicts with other code and the crash

This behaviour is what I would expect. The graph is created at

Quote:
%pl[native,framed,x_array,scale=log_log,N_GRAPHS=1]


so the following
Quote:
%pl[gridlines]
comes too late for this graph.

You can use winop@("%pl... ) multiple times before winio@("%pl...) but you can only use the latter form once for each graph.
