| ☜ | postcondDraft MDC Standard | ☞ | ||||
All commands except Else, For, and If may be made conditional as a whole by following the commandword immediately by the post-conditional postcond.
| postcond | ::= | [ : tvexpr ] |
If the postcond is absent or the postcond is present and the value of the tvexpr is true, the command is executed. If the postcond is present and the value of the tvexpr is false, the commandword and its arguments are passed over without execution.
The postcond may also be used to conditionalize the arguments of Do, Goto, and Xecute. In such cases the arguments’ expratoms that occur prior to the postcond are evaluated prior to the evaluation of the postcond.
