concat, set, {add,sub,mul,div} implemented.
The following instructions will now work as in perl5...set P0,3 set P1,"foo" concat P0,P0,P1 # "3foo" set P0,3 add P0,P0,P1 # 3 set P0,-13.3 set P1,"13.3" add P0,P0,P1 # 0 (even though P1 is a string) The code for add/sub/mul/div has to be able to be simplified somehow. It passes the requisite tests so I'm calling it good for now, but there's probably a very simple optimization that I'm missing at 1:30 A.M. -Jeff <[EMAIL PROTECTED]>
