OK, I found an error within my script and the "abort"-command works again but only more or less... See for instance the following code:
A = 2;
B = 5;
C = 8;
Before I run the script in the freshly started Scilab I can use the Console normally - hence, If I write A = 2 and hit return it creates the variable and displays the value of A in the console window.
If I run the script I only see that it was performed but I do not see any new variables in the variable-browser. Only after, for instance, typing a 1 in the console window and hitting return I see that the script actually did something, as A and B are defined (C is not, as it is supposed to be).
However, now after having run the script I cannot use the Console-Window properly anymore.. I still can use it to define variables or perform calculations but the results are never displayed in the console. It is if every command I input would have the ";" at the end.... This is annoying, as only rebooting Scilab helps in that case..
Maybe if it helps, here is what the console displays upon Scilab-Startup:
START GUI Builder 4.0.1 for Scilab 6.0
Type "guibuilder" to start the GUI
Start IPCV 1.0 for Scilab 6.0
Image Processing and Computer Vision Toolbox for Scilab
