This is no special coding and similar tasks will arise sooner or later to everyone. What changes in the firmware might cause the result? How should I code a problem like the original one and what did I get wrong with the patch note about finally integrating the cas into home??

Code:


EXPORT tst()
BEGIN
local argument,result;

//version1 result is [undef]
//argument:="b^2=10,b";
//CAS.solve(argument);

//version2 result is "solve(b^2=10,b" i.e. the call
//argument:="solve(b^2=10,b)";
//CAS(argument);

//version 3 result is [b^2=10 b]
//CAS("b^2=10,b");


END;

P.S:
F1:="B^2=10";
RETURN solve(F1,B);

Does the trick, BUT(!) that is really unintuitive and no improvement and I am sure that there must be an other way. And second it is totally different from what the other posters suggested i.e. useing lower case letters.... because F1:="b^2=10"; solve(F1,b) in all variants fail with syntax errors.

So I am curious about what is going on.

My suspicion is that you do not have a clear understanding of variable types and their priorities. B is a system-wide variable whereas b is generally not (it must be created). Moreover, when you use F1:="b^2=10" this will likely generate and internal syntax error if b does not already exist as a variable.
