Change the way LOCAL variable declaration works.

[Han]

You can create CAS variables and clean them up afterward. Keep your variable names as strings, and initialize them through the CAS.

Code:


vars:={"a", "b", "c"};
tmp:=vars(1)+":=0";
CAS(tmp); // use a for loop to init all the vars if you want to init all of them

// do your stuff 

purge(vars(1));

You can also create a corresponding list of default values if you don't want to initialize to 0.
