(Mostly for Bernard)

I am aware of the ability for XCas to switch to maple and ti mode for code compatibility. I was wondering if there is a similar mode switch so that one may simply copy HP Prime CAS programs directly from the calculator/virtual calculator into XCas and run it directly.

At the moment, I have to to manually change all BEGIN-END pairs for code blocks to { and }:; and lower modify indices of matrix[i,j] to matrix[i-1,j-1]. The HP Prime code resembles maple syntax for some things (indices) but not everything (equality checks are == on the Prime and = in maple) so it seems maple compatibility mode does not work directly.

Any suggestion?

Try calc_mode(-38). If there are keywords not recognized please list them. BEGIN/END should work in Xcas, you don't need to replace by { }

I seem to have run into a very strange roadblock.

Copying the following line from Maple (and remove the "Matrix( )") gives me errors in line 10 and at various columns...

Code:

M:=[[44,48,82,48,55,-65,-20],

[72,-86,-16,77,-46,-28,-28],

[23,-26,-46,-87,88,6,-16],

[14,69,71,-78,-74,81,-27],

[-87,81,-88,51,-8,68,48],

[-46,-59,-69,84,31,45,-28],

[99,84,56,-66,92,-31,-63],

[33,44,93,-37,-20,39,-4],

[-40,-48,10,-58,31,78,81],

[-22,10,-26,-97,37,-9,-54]];

This is related to unary vs binary minus (was introduced for the hp39gii). I can easily modify the parser in Xcas and remove that constraint. You can replace - by 0- and it should work.
