Example:
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)
→ // LIB [0] string standard.lib,general..., 74 char(s)
killall("ring"); // kills all rings
→ // ** killing the basering for level 0
listvar();
→ // j [0] int 3
→ // str [0] string hi
→ // LIB [0] string standard.lib,general..., 74 char(s)
killall("not", "int"); // kills all variables except int's (and procs)
listvar();
→ // j [0] int 3
→ // LIB [0] string standard.lib,general..., 74 char(s)
killall(); // kills all vars except loaded procs
listvar();
→ // j [0] int 3
→ // LIB [0] string standard.lib,general..., 74 char(s)
