As far as I can tell, the most surefire solution is to run a Maple version only on an operating system (OS) which is or was officially supported for that version. A possible alternative might be to ensure that the glibc (and/or X runtime libs) as well as the JRE will match those of one of the officially supported distributions.

I have only seen the problem you describe on Linux distributions which are somewhat older that the officially supported ones. Perhaps you could try running your Maple 12.02 on a more recent distribution.

note: a clarification for anyone else reading, based on some earlier responses. This is not a problem with 2D Math output, or with any output. It's a redraw problem in the Standard GUI in which the whole session goes blank and is unresponsive for about 5-10sec merely upon pasting in input. It could even be 1D input pasted to a Worksheet, with trailing full colon.

Well, exactly. And most of it is in the same highly inefficient style, so no wonder it is slow.

I'm not sure that it's good form to post other people's complete programs (especially when a link is possible, as Axel showed.)

I looked at SHA_ROTL, and then could not look at the rest.

These ideas seem to suffer from skewness, either in placement of the values toward an endpoint or in respect to the distribution of the size of the jumps (while the combinat solutions apparently don't).

Very nice.

Can it stay so simple, while getting the ability to restrict the maximum stepsize as the submitter mentioned in a postscript?

If you add the location of your new .mla Library archive to libname, then you ought to be able to access its contents. The ?libname help-page gives examples (Unix, but easy to adjust for MS-Windows style paths).

The command to modify the read-write permissions of a Library archive is LibraryTools:-WriteMode. Trying to use that on Maple's own installed archives would generally be a very bad idea.

Adding custom written prodecures to private archives, and reusing them after augmenting libname, is common practice. There should be no need to overwrite anything in Maple's own archives (even patches and fixes aren't implemented as direct in-place edits, but are pushed out as alternate versions in a new archive which gets found first by having a higher internal access-priority).

Names commonly returned by anames(user), in which you are not interested, can be removed from your inquiry.

> T:=5*Unit(degF):
> setattribute('T',"temperature"):
> L:=[4,5]:
> V:=Vector(L):
> setattribute('h',"height"):
> eqn:=T*h:

> p:=proc() local x;
>   seq([x,whattype(eval(x)),[attributes([x][1])]],
>       x in {anames('user')} minus {'lasterror','lastexception',:-p});
> end proc:

> p();
 [L, list, []], [T, *, ["temperature"]], [V, Vector[column], []], [eqn, *, []]

Note that name `h` is not reported, since it has not been assigned a value.

I think that he just ran into a name instead of a string.

> X:="18DBD3547552C73BE4DE87731C500":
> num:=convert(X,decimal,hex);
               num := 8067107224306383990011936212370688

> convert(num,hex,decimal);
                     18DBD3547552C73BE4DE87731C500

> lprint(%);
`18DBD3547552C73BE4DE87731C500`

Procedure `p` can work with names as well as with strings, since `cat` and StringTools:-LengthSplit can also.
