breakpoint;

This is normally written on a separate line. When playing a transaction, the running of the script will "break" when it comes to the breakpoint. From there the user can use the following four buttons to step through the script:

• Step into
• Step over
• Step out
• Play

Once the script gets to the end, you must press play to exit the debugging window. Many breakpoints can be added to scripts. Pressing Play will play till the next breakpoint , an error, or the end of the script. Stepping over lets you step over a function rather than stepping into it.
