> The output of "undefined" is normal.  It is the result of the expression you entered.  jsc is basically returning the result of the expressions you enter.  Both var and print themselves evaluate to "undefined".  If you try "x = 1;" you'll get 1 as that expression returns 1.

This script will first run testapi, which tests the JavaScript APIs and then run a collection of javascript tests.  If you have successfully built testRegExp, you can run run-regexp-tests which will test the regular expression engine.  Both testapi and testRegExp should be built along with jsc when you run the script Tools/Scripts/build-jsc.
