| | LIB "general.lib";
ring rtest; ideal i=x,y,z; string str="hi"; int j = 3;
export rtest,i,str,j; //this makes the local variables global
==> // ** `rtest` is already global
==> // ** `i` is already global
==> // ** `str` is already global
==> // ** `j` is already global
listvar();
==> // j [0] int 3
==> // str [0] string hi
==> // rtest [0] *ring
==> // i [0] ideal, 3 generator(s)
killall("ring"); // kills all rings
==> // ** killing the basering for level 0
listvar();
==> // j [0] int 3
==> // str [0] string hi
killall("not", "int"); // kills all variables except int's (and procs)
