You shall use:

save mySessionFile
load mySessionFile

The application has no function to guess or read users minds and post a 
report accordingly.
It has not yet any embedded A.I. to do so.

Simplicity is not necessarily relevance nor justification.

O wise words :)

Obviously not. Other language, other scripts.

But just, Matlab and Scilab are not compatible. Adding % comments would 
not make then compatible.
It is not a matter of more or less compatibility.

So, you wish to build a kind of computing esperanto.
Could you please give us a pointer to your wish certainly posted on 
Octave mailing list or bug tracker to support "//" as comment as well? 
Look at this Octave session:
 >> // a comment
parse error:
   syntax error
 >>> // a comment
     ^
What a shame! And a potential loose of manpower! Don't you think?
And try with "#" that is another symbol used for comments in other 
widespread languages.
The same! So bad is the world.

It was not very clear the first time i read (and reread) it, but now 
it's ok (likely). In:

--> consoleSetProfile(“my-color-profile”);

--> disp(data)
1. 2. 20.
1. 2. 17.
7. 6. 18.

the most important is consoleSetProfile(“my-color-profile”); where the 
prerequisite is to have set your specifications (i guess).

Excepted for the colors, you can do this in Scilab by defining your own 
Disp() that will preprocess your input data before calling disp() or 
mprintf() to actually display them.

About colors in the console, your skills and time are certainly welcome 
to process this report:

Yah, in life, some things may be modular. In computing sciences too.

Yes, why do we need two teams to do two jobs of complexities 1 & 1, 
while we would need one single team twice bigger to do a single job of 
complexity exp(1+1) in exp(1+1)^2 /(1+1) more time?
(i have no pointer to give about this patatheory, but i think it could 
be relevant to answer to your need.
BTW, it is an open and free one with no copyright, to relieve your budget).

Not really. Just think about manpower sinkholes.

Could you give more details? I do not see how it could be so. AFAIK, 
this language does not include any formal interpreter nor formal to 
numerical converter. Does it?
