The previous example showed how to run a TI-BASIC program from an
application. If an application just needs to execute a function or expression to
return some value then the following example will do that. The function
tCmdLineDriver below inputs a string from the user using a dialog box. It then
calls the function CmdLine to execute that string and return a value. The return
value is stored to a global variable, E1. If there is an error then an error dialog is
displayed. The CmdLine function will evaluate the string and return a value on
the estack. It will not evaluate anything that has side effects — that is the
