The break statement enables or disables the BREAK key.
break [off|on|exp]
| off | Disables the BREAK key. |
| on | Reverses the effect of the last executed break off statement. If multiple break off statements are executed, an equal number of break on statements must be executed to return to a breakable state. |
| exp | In the expression form, the BREAK key is disabled when exp evaluates to 0 (false), and enabled when exp evaluates to nonzero (true). |
The BREAK key, if enabled, interrupts the current process and either invokes the FlashBASIC or BASIC debugger or pushes a level.
The expression following break must evaluate as numeric or this run-time warning message displays:
[b16] in program "pgm", line n: Nonnumeric data when numeric required; zero used.
If the value of user is fred, this has the same effect as issuing the TCL break-on command.
