Alt-A - Animate
 Run the program automatically a line at a time.
──────────────────────────────────────────────────────────────────────────────

 Set the program to step through the program one line at a time, updating all
 windows and all the information contained within those windows.

 This has the effect of single stepping automatically through the program.
 All windows, including the call stack, the variable and source code windows
 are updated to reflect the changes as the program steps through executing
 each line of code.

 Execution of the program will stop either when the program ends or, an error
 occurs or, a break point is reached, an ALTD() is executed, a trace point is
 activated, an error occurs, or you press <Alt><D>.
